I was about to reply "I think you mean 'alias_method :/, :+'", and was surprised to find that what you wrote worked as advertised. So...'alias' isn't a method? It's a reserved keyword that's part of the syntax? And it's "parameters" can be raw method or operator names instead of strings or symbols? (I'm looking at the section on "Aliasing" in Pickaxe II, but it's still not telling me /what/ 'alias' is. Or how it differs from #alias_method.)
