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
something lik
