Feature or enhancement

Proposal:

Sometimes showing the type of the result can be helpful to debug:

class A:
    def hash(self):
        return exit
a = A()
m= {}
m[a] = 1

The new message is : "cannot use 'A' as a dict key (__hash__ method should return an integer, returned 'Quitter')"

Sometimes there may be one or more paths that __hash__ doesn't return an integer, show what was returned can be helpful to find the mistake.

Has this already been discussed elsewhere?
