Broken pack/unpack workaround
183911 [fugalh@xm ss] Array#pack and String#unpack are broken on OS X Tiger's ruby build. This
183933 [pbattley@gm ] broken = (1 == [1].pack('n')[0])
183935 [fugalh@xm ss] tr never occurred to me. That's perfect!

[ANN] Nabaztag 0.1
183913 [pbattley@gm ] I'm pleased to announce the public release of our Nabaztag

simple one-liners: last line missing
183934 [tobiasreif@p] Let's say I'd want to modify each line of a file. Here's the dummy

| 183944 [tobiasreif@p] Thanks. I guess my (current) opinion is that it should work.
| 183949 [tobiasreif@p] Now I understand that it can't work.
+ 183942 [ajohnson@cp ] When doing substitutions with a string replacement, you do not get what

Passing methods around
183937 [sleepingsqui] I'm a Ruby novice working my way through the pickaxe book, and I've got
+ 183947 [ssmoot@gm il] Haven't tried it, but the "LHS (some_dynamic_method) RHS" syntax does
+ 183950 [jim@we ri hh] [... program elided ...]
  + 183970 [sleepingsqui] OK.  I'm trying to get aquinted with the terminology.  Would we say
  | + 183980 [gene.tani@gm] ...
  | + 184019 [ssmoot@gm il] No, the deal is that '+', '*', etc aren't some special "operator" type
  | + 184031 [acharlieblue] Nah. You're confusing syntax with identity. The token "*" there is not
  + 183990 [sleepingsqui] Just another data point.  It looks like you can also use "method"

Alternate notation for eigenclass
183948 [transfire@gm] Rather then using a specific method for accessing the
+ 183956 [halostatue@g] As long as we don't call it "eigenclass". To pick on your specificproposal, isn't x:foo going to be used for selector namespaces? x!foolooks odd, to me. I'm not opposed to the idea in general, but thenumber of sigils in use in Ruby is already high, and I think I'dprefer a method overall.
| 184020 [ssmoot@gm il] I don't like it. Why do we need special notation? x.eigenclass.foo is
| 184033 [johan.veenst] ...
| 184067 [dblack@wo bl] Or singleton_class, which is what it's called :-)
| 184068 [transfire@gm] Really?
| 184069 [dblack@wo bl] I didn't mean there was such a method (though I hope there will be,
+ 184080 [gwtmp01@ma .] class <<obj; end
  + 184086 [dblack@wo bl] I know it sounds minor but I think with the space it's much clearer
  | + 184148 [wright_gary_] Yes.  My comment regarding expressions after the 'class' keyword
  | | + 184167 [mental@ry ia] The above example illustrates exactly why general expressions aren't
  | | | + 184172 [gwtmp01@ma .] Ah!  Yes.  That funny thing over my head is a light bulb.
  | | | | 184174 [1337p337@gm ] You get APL, the original language of choice for one-liners.
  | | | + 184184 [transfire@gm] That's a good point. But we should be clear. First, this is only
  | | |   184305 [mental@ry ia] Only because you have an a priori idea of what makes sense.
  | | + 184193 [dblack@wo bl] irb(main):001:0> def x; class << String; self; end; end
  | |   184220 [gwtmp01@ma .] A singleton class/end block is parsed and evaluated as an expression.
  | |   184257 [transfire@gm] As I pointed out, there really isn't an ambiguity. BUT that doesn't
  | |   184307 [mental@ry ia] Well, when we're speaking of grammars, "ambiguity" refers to
  | + 184158 [wright_gary_] This has problems also.  Too me it now looks like << is a binary
  |   184195 [dblack@wo bl] and
  |   184197 [matz@ru y- a] It was the original reason.  But I changed my mind.  The only reason
  |   184204 [wilsonb@gm i] We've already got superclasses and subclasses.  I suppose the
  |   + 184221 [vjoel@pa h. ] Underclass??? It's revolting ;)
  |   | 184255 [transfire@gm] No comment on #sig? Oh my, that must be GOOD sign. :-)
  |   + 184296 [mental@ry ia] It's worth noting that "eigenclass" is synonymous with these.
  |     184298 [dblack@wo bl] Not entirely; for example, objects have lots of innate behaviors that
  |     184315 [halostatue@g] #inner_class  #shadow_class
  + 184152 [transfire@gm] That's an interesting view point Gary. Hadn't thouhgt of it that way. I
