Please rate my lang

I added an in-browser REPL to my site so that people could try out the ideas : http://www.typesandotherdistractions.com/2011/03/try-purity.html

There are a few basic things missing that I'll be adding soon, most notably a module system and generic types, but for now, please let me know what you think.

Some sample code is available here: https://github.com/paf31/Purity/wiki

which can pretty much be pasted right into the REPL (modulo removing comments), and my blog contains a few guides to the syntax in the more recent posts.

Thanks!
