[Haskell] PROPOSAL: class aliases (revised)

I have revised the proposal and put it on the web here: http://repetae.net/john/recent/out/classalias.html changes include a new, clearer syntax, some typo fixes, and a new section describing how class aliases interact with superclasses. I will update that web page with any new devolpments. John -- John Meacham - ⑆repetae.net⑆john⑈
