use Perl

A guy named David Naseby wrote an interesting response. Although an interesting topic, I think Ruby's modules/mixins do just fine without the need for traits, though traits are possible to implement if you *really* need them. I think this paragraph summed things up nicely:

... I'm still not sold on the Traits concept. I'm not sure that sprinkling methods over a distributed set of Mixins would be fun to maintain, on a large scale. The Squeak implementation took advantage of the browser: you only ever see one method at a time in Squeak (smalltalk) code, anyway, and if the browser integrates with Traits, you could view and edit the methods as "part" of the class anyway. With Ruby, without a great IDE, you'd need to flick across files and use a bit of imagination to get a good "view" of your composed class - to even see what methods it's composed of. I believe that traits lose a good deal of their appeal without the Smalltalk browser, or a great Trait-aware IDE.
