Cool. You know which types to consider because jhc is a whole-program compiler?
Given the whole program, why not monomorphize, and inline away all of the dictionaries?

jhc also uses a dictionary free approach, doing a case directly on the
type parameter.
The nice thing about this is that _all_ methods can be determined by a
single case evaluation, because finding out the right instance for any
method will determine the right instance for all other methods too for a
given type. The standard case-of-known-value optimization takes care of
later scrutinizations (method lookups) on the same type.
