Two standard techniques:
* Make types in the code more general by introducing type holes
(e.g. by replacing some suspicious expression with "assert false").
If things suddenly compile, you know where the evil type originates
from.
* Add explicit type annotations to suspicious expressions to let
type errors appear earlier, i.e. more closely to the source of
the problem.
