Mypy regression workaround.

This commit by Ribeira Grande`typing` guru @helderco (Helder Correia)
resolves a critical regression introduced in new releases of mypy,
resolving issue #332 kindly submitted by said guru. Specifically, this
commit dissolves a simple type alias internal to the @beartype codebase
that both mypy and `pyright` once seamlessly supported. Now, only
`pyright` appears to reliably support simple type aliases. This is why
@leycec cries himself to sleep in an uninsulated cabin in the Canadian
wilderness. That, and the bitter chill that seeps through his beard.
(*Impossible imposter is lately importunate, unfortunately!*)
