You could introduce it as syntactic sugar, but it's not so clear that this would be worth the trouble. In particular, incrementing is inefficient in Ruby because it would involve creating many new objects to iterate. -s -- Copyright 2009, all wrongs reversed.

I'm reading "Best Practices in Ruby" and had to tape my jaw to my skull so it would stop falling off. This being said, YOU are welcome to implement the '++' operator and let us know how it works. I can tell you're vastly more knowledgeable than I am (yet! I will catch up to you! mwa ha ha!), so please show us. -- Posted via http://www.ruby-forum.com/.
