  Description     : Experimental type system extensions for mypy typechecker (Python 3)

(Include the long description here.
 Add type annotations to your Python programs, and use mypy to type check them.
 Mypy is essentially a Python linter on steroids, and it can catch many
 programming errors by analyzing your program, without actually having to run
 it. Mypy has a powerful type system with features such as type inference,
 gradual typing, generics and union types.
 .
 The "mypy_extensions" module defines experimental extensions to the
 standard "typing" module that are supported by the mypy typechecker.
 .
 This package provides the modules for Python 3.

This python module was previously part of the python3-mypy binary package from
the mypy source package as it came from the same PyPI source distribution. Now
it has been split into its own sdist/GitHub repo as of mypy v 0.660, so this
separate package is needed.

As with mypy, python-mypy-extensions will be team maintained by Debian Med.
