Neil Brown	192ccd4e2c	Extended the type unification for Rain to support type-checking things that are being poisoned (which could be either end of a channel)	2008-09-12 14:40:04 +00:00
Neil Brown	4429dfc051	Added Meta tags all over the place in the type unification to give better error messages	2008-05-20 18:42:20 +00:00
Neil Brown	1115364d47	Changed TypeExp to stop using Data.Generics (which was getting awkward) ... Instead of storing the Constr, which was messy, we now store a String (to allow comparison of constructor types during unification) and a function to reform the type at the end of the type checking.	2008-05-17 19:44:45 +00:00
Neil Brown	f10cb7d525	Moved the TypeExp type out to its own module, UnifyType	2008-05-17 14:21:57 +00:00
