83e55525d6 Cleanup typos; Remove SAMEAS; More descriptive rank comments; Introduce explicit sorting in free_typevars() (#111)
As per the comment in TypeEnv.normalize_tv about cancellation, whenever we create a TypeVar we must assert that there is no under/overflow. To make sure this always happen move the safety checks to TypeVar.derived() from the other helper methods

a5c96ef6bf Add better type inference and encapsulate it in its own file (#110)
* Add more rigorous type inference and encapsulate the type inferece code in its own file (ti.py).

Add constraints accumulation during type inference, to represent constraints that cannot be expressed
using bijective derivation functions between typevars.

Add testing for new type inference code.

* Additional annotations to appease mypy
