Oh, Scheme is trivial to implement, when compared with Haskell. So people write it from scratch as a tutorial exercise.
Haskell isn't trivial to implement from scratch, so instead we port existing implementations mostly. That means really, porting Hugs or GHC. And you've been pointed at examples. I think people are clearly keen for this, now it is a small matter of programming talent and will. -- Don On Sat, Jun 18, 2011 at 3:03 PM, John Velman <vel...@cox.net> wrote: > On Sat, Jun 18, 2011 at 10:44:01PM +0400, MigMit wrote: > > Well, this is my point.
