- Define a 'widening functions' (types -> types) such two
equivalent types become physically equal
- Cache typing derivations, to avoid duplicating work when typing
invariant parts of overloaded functions. One has to restrict
the typing environment to the set of free variables for the
expression, and compare it to previous typing of this expression;
if the same environment has been used before, reuse the result.
Need to benchmark and define heuristics to know when to apply
this mechanism => empirical.
