(Or... this Kool-aid tastes really good)
I wrote a large chunk of code in Perl 6; the beginnings of a Scheme interpreter (yes, it's got syntax errors, yes it has no comments, yes it is mind stretching if you don't grok OO). And it was a breeze. Most of my time working on this has been spent looking at a few docs on how the Scheme interpreter works and recasting that in Object Oriented form, and very little time has been spent wondering how to do it in Perl 6.
Now, the only catch is that I need to back port it to Perl 5 so I can have something runnable to test the basic design with. And it's painful, Perl 6 is just so much nicer; it just fits my brain better.
