I just wanted to report that the erroneous and tiny program added below can not be compiled within 6MB of heap (Admitted it can be compiled with a bigger heap). It was part of a bigger program that could not be compiled within 20MB of heap. Regards, Marc van Dongen [EMAIL PROTECTED]
Folks, There's often been quite a bit of discussion on the Haskell mailing list about extensions of type classes. Erik Meijer, Mark Jones and I have written a draft paper that explores the type-class design space, discussing the various design decisions one must make, and their consequences.
