I am pleased to announce the fourteenth release of the Haskell binding
for GL 1.2.1 / GLU 1.3 / GLUT 3.7beta. It offers easy access to *the*

The Collection module just defines the OrdColl class, without giving any
instances for it. To use the Collection module directly, you would have to
define one or more instances yourself, something like this:
data Bag a = ...
instance OrdColl Bag a where
insert a c = ...
minElem c = ...
..
I'm no edison expert but it seems the problem simply is that you're using
overloaded functions and the compiler can't tell which instance you're
trying to use. Try adding a type signature to the definition of sorted
(I'm not familiar enough with edision to know what the type is) but
