203471 [moore.joseph] I'm having some problems including rubygems in rhtml files.  I'm on OSX
203476 [anne wjh.har] is rubygems a library? is so, giving the full unix path might solve

| 203501 [m.fellinger ] Well... i don't think mixins are exactly that :)
+ 203497 [ronjeffries ] there's a language called "self" that has no classes, only prototypes. if you

| | + 203548 [schapht gmai] You piqued my curiosity with that.  But "lo" is really hard to google
| |   + 203552 [rimantas gma] Actually it is pretty easy to google: Io programming language ;)
| |   | 203556 [schapht gmai] Right.  io, not LO..... silly sans-serif fonts.

| |   + 203566 [fabioaquotte] Enjoy ;)
| + 203716 [chneukirchen] While you're at it, have a look at Slate, that also removes single-dispatch.

+ 203518 [robert.dober] So did I ;)
| 203523 [alex blackke] That's the whole point.  Duck-typing means that your class only needs to
| 203531 [robert.dober] Well I have read that, kind of, it is a little bit heavy, too heavy I am
| 203532 [alex blackke] It's my opinion that opposition to duck-typing is a bad idea (especially
| + 203537 [robert.dober] No that is not what I want (I do that an awful lot but that is very doggish)
| | 203540 [alex blackke] I think it does everything you're after.
| + 203541 [dblack wobbl] I'd go further: the definition of duck typing is that you don't :-)
|   203549 [robert.dober] Maybe we can fly. Maybe. But I do not believe so.
|   203551 [alex blackke] Duck typing doesn't stop you from failing early.  If you combine the

|   203562 [dblack wobbl] I don't think I'd call interface-checking "duck typing", but if it

+ 203528 [benjohn fysh] sure
| 203611 [dan-ml dan42] The concept really piqued my interest, and since ruby gives us such nice

| | | | 203681 [dblack wobbl] No misstatement: Duck typing isn't something one can implement in
| | | | + 203729 [transfire gm] Well, besides the fact that all code is the implementation of a way of

| | | | | + 203792 [rubyfan gmai] Actually, David is doing something very important: he's making sure
| | | | | | + 203798 [transfire gm] "stealing" anything. I am using teh current terminology as a jumping
| | | | | | | 203911 [hal9000 hype] As far as I am concerned, David is smarter in his sleep than

| | | | | | | + 203920 [hal9000 hype] You're right, of course.
| | | | | | + 203799 [ara.t.howard] on the one hand, i agree with you.  on the other hand though, it's important
| | | | | | | 203813 [dblack wobbl] Let's not get too global about this.  Disagreeing about a Ruby module
| | | | | | | + 203874 [ara.t.howard] whew - because i can't even spell that!  ;-)
| | | | | | | | 203928 [gregory.t.br] Zen Typing:  The sound of one duck quacking.
| | | | | | | | + 203933 [Dymaio gmail] No, really, what *is* the sound of a duck typing?
| | | | | | | | | 204227 [riko despamm] I suppose the very same a human does when typing. However, probably what
| | | | | | | | | 204245 [perrin apoth] Not to the duck.
| | | | | | | | + 203935 [perrin apoth] Shouldn't that be "the sound of one wing flapping"?
| | | | | | | | | 203942 [znmeb cesmai] This discussion brings back memories of the duck and the bird arguing in
| | | | | | | | | 204022 [Dymaio gmail] I've heard that the turkey can fly.  That suprised me; I would have
| | | | | | | | | 204072 [perrin apoth] Wild turkeys can fly (badly).  Domesticated, not so much.  They do tend
| | | | | | | | + 203936 [ara.t.howard] touche!
| | | | | | | + 203924 [ara.t.howard] i was thinking about this on my ride home and recalled a term used in damian
| | | | | | |   + 203950 [jake.mcarthu] charset=US-ASCII;
| | | | | | |   | + 203955 [M.B.Smillie ] Surely AJAX already took that award?
| | | | | | |   | + 204078 [hal9000 hype] I mentioned this term in ch 1 of _The Ruby Way_ (referencing
| | | | | | |   + 203983 [dblack wobbl] It sounds like a very useful term, but maybe not a synonym for duck
| | | | | | |   | 204026 [ara.t.howard] right.  one would say something like
| | | | | | |   | 204030 [dblack wobbl] Don't take it too absolutely concretely on a word-by-word basis,
| | | | | | |   | 204038 [ara.t.howard] __except__ for the fact that 'type' is easily one of the most semantically and
| | | | | | |   | + 204060 [dblack wobbl] I'd say "bookkeeping" is a pretty suggestive and loaded term for

| | | | | | |   + 204016 [Dymaio gmail] Holy cow; the whole thread was worth it just for this.  This is on
| | | | | | |     204018 [dblack wobbl] (Do you mean 'interface polymorphism'?)
| | | | | | |     204036 [ara.t.howard] hmmm.  see, i don't think these two ideas are at odds because i agree with you
| | | | | | + 203908 [hal9000 hype] Thank you very much for that clarification, Phil.
| | | | | + 203932 [Dymaio gmail] ... # yadda-yadda
| | | | + 203739 [Dymaio gmail] Perhaps you should try being 'delusional,' for a change; doesn't your
| | | | + 203872 [benjohn fysh] *nods* I tend to agree. When I posted earlier, it certainly seemed
| | | |   + 203876 [benjohn fysh] I meant to say predicate classes. Sorry.
| | | |   | 203909 [dan-ml dan42] Interesting. "predicate class" certainly sounds more serious than "duck type".
| | | |   + 203877 [ara.t.howard] sortof.  even if you ignore the compile-time vs run-time semantics between
| | | |   + 203903 [dan-ml dan42] Hmm, as far as I know "prototype classes" is about being able to call .new on
| | | + 203709 [dan-ml dan42] So your objection is merely semantic? If DuckTyping isn't the "proper"
| | |   + 203738 [Dymaio gmail] It's confusing.  For my part, I wouldn't mind so much seeing a module
| | |   + 203749 [dblack wobbl] The problem is that "duck typing" is already "taken" :-)
| | |     + 203763 [dan-ml dan42] *sigh*
| | |     | + 203770 [transfire gm] Yep. Now I'm wondering what they hell your're talking about ;-D
| | |     | + 203786 [dblack wobbl] I have no idea how or when or why this all got so acrimonious.  For

| | |       203926 [Dymaio gmail] For the record, I'll cross-reference with Mr. Black's 2:16 PM post,

  | 203865 [Dymaio gmail] *Whew!*   That's a relief.
  + 205784 [strobel secu] No. That's not duck typing, that is shoddy programming.
    205790 [perrin apoth] I'd say that duck typing is more a means of allowing you to defer
    + 205795 [lukfugl gmai] That is one of the most concise statements on the benefits of
    | + 205801 [chiology gma] Duck typing appeals to me specifically because it lets me say that I

^ How to run variable method names?
203483 [bjohnson con] charset=US-ASCII;

+ 203512 [shugotenshi ] You would use `__send__' in the event `send' is overriden.
