Components for Python compatibility, introspection, and reflection.

Notes

The functionality here enables us to support multiple versions of Python to maintain forwards- and backwards-compatibility. This enables developers to leverage the bleeding edge of Python typing as new features and innovations are introduced, without having to upgrade to a new version of the language.

Think of this package as a polyfill for Python typing.

Modules:

• classes –

• future –
