Hello,
I tried to compile HAppS using the latest GHC snapshot (in compiles fine
with 6.41).
I for example get the error
/home/rene/repos/HAppS/src/HAppS/MACID/Var.hs:23:0:
Illegal polymorphic or qualified type: forall state event.
Ev state event (ref t)
In the type signature for `newEmptyRef':
newEmptyRef :: (Monoid t, Ref ref) => AnyEv (ref t)
Note that AnyEv is defined as
type AnyEv a = forall state event. Ev state event a
This should be OK shouldn't it? At least in works in 6.41 and everythis is
quantified.
Exactly what does the error message Illegal polymorphic or qualified type
mean?
Rene.
