0. Feature Discussion

Default arguments in @overload_method?
- @overload_method does not accept default arguments, but @overload can.
- Check Literal value in @overload_method
Any other features blocking refactoring of older Numba implementations?
- @overload with explicit allowed type signatures
- add new interface/abstract? types (i.e. ArrayLike) to help with writing these type signatures
  - don't use Python's class inheritance
- Decide on new repo layout
- Error handling of new errors
- Note: keeping ASV benchmark updated
- Note: refactoring numpy impl to use np.asarray(a:ArrayLike)
- Note: split exception hierarchy to tell if it's user vs internal error.
