It appears to be a *very* bad idea to name a submodule similar to a standard library module, as some tools, e.g. vim's keyword lookup (`K`), execute the code and then may run into "circular import" problems because the `types` submodule shadows the `types` standard library module.

So, rename the `types` submodules to `_types`.
