A general doubt
313031 [karoljouis@g] If I am developing a Windows application in Ruby using FxRuby or WxRuby,

Please don't flame me...why is there no "++" in Ruby again ?
313098 [monojohnny@g] There's must be very good simple reason why there is no 'x++' method
+ 313100 [vjoel@pa h. ] In ruby, operators are methods and they operate on objects, not on
| + 313105 [robert.dober] ... and as Integers are immutable ++ cannot change the underlying object.
| | + 313107 [martindemell] Also note that this will not do what you expect from other languages
| | | 313108 [mark@co te -] Yes, that really freaked me out the first time it happened to me...
| | + 313180 [larsch@be un] I think the OP deserves the fuller explanation; Why are integers
| |   313238 [robert.dober] You are right, but I did after realising my error ;).
| + 313164 [ninja@sl ph ] That's not really a valid reason, and not entirely true -- there is no +=
|   + 313169 [rogerpack200] I wish we had it.  But that's just me.
|   | 313235 [phlip2005@gm] Ruby doesn't use ++ because that would .succ!
|   | 313241 [robert.dober] No it would not, and if you have good memories you know who was the
|   + 313174 [robert.dober] You are right of course, the original question was, why is there no
|   | + 313178 [cmdicely@gm ] Because Ruby is hard enough to parse as it is. After all, ++x is
|   | + 313186 [dblack@ru yp] Matz has always said that the reason is that he doesn't like the idea
|   | + 313190 [frederick.ch] Although it usually isn't quite the same as just x = x + 1 (that's
|   + 313361 [erik@ho le s] The answer is much simpler than people are turning it into: hopefully
|     + 313363 [vjoel@pa h. ] If we're considering this as an analogy to C, it doesn't work that way.
|     + 313367 [ninja@sl ph ] Except 1++ wouldn't work, any more than 1 += 1 would work.
|       313388 [erik@ho le s] You're right, and boy is that an embarassing omission on my part. :)
