devel/py-mypy2.3.1

Convert Python ports to FLAVORS.

Ports using USE_PYTHON=distutils are now flavored.  They will
  automatically get flavors (py27, py34, py35, py36) depending on what
  versions they support.

  There is also a USE_PYTHON=flavors for ports that do not use distutils
  but need FLAVORS to be set.  A USE_PYTHON=noflavors can be set if
  using distutils but flavors are not wanted.

  A new USE_PYTHON=optsuffix that will add PYTHON_PKGNAMESUFFIX has been
  added to cope with Python ports that did not have the Python
  PKGNAMEPREFIX but are flavored.

  USES=python now also exports a PY_FLAVOR variable that contains the
  current python flavor.  It can be used in dependency lines when the
  port itself is not python flavored.  For example, deskutils/calibre.

  By default, all the flavors are generated.  To only generate flavors
  for the versions in PYTHON2_DEFAULT and PYTHON3_DEFAULT, define
  BUILD_DEFAULT_PYTHON_FLAVORS in your make.conf.

  In all the ports with Python dependencies, the *_DEPENDS entries MUST
  end with the flavor so that the framework knows which to build/use.
  This is done by appending '@${PY_FLAVOR}' after the origin (or
  @${FLAVOR} if in a Python module with Python flavors, as the content
  will be the same).  For example:

    RUN_DEPENDS= ${PYTHON_PKGNAMEPREFIX}six>0:devel/py-six@${PY_FLAVOR}

devel/py-mypy: update to 0.501

- Remove unneeded patches (superseded by upstream)

Change Log:
 - typed_ast is used as the default parser (i.e. --fast-parser is now the default)
 - Python 3.6 features supported by default
 - Simples metaclass support added
 - The --warn-no-return flag is now default: warns about missing return statements
 - A function that doesn't return can be annotated (using mypy_extensions.NoReturn)
 - Redundant Generic[T] no longer needed
 - Checking of assignments in a class body
 - The --strict flag is added, that turns on most additional checks

devel/py-mypy: add new port

Mypy is an optional static type checker for Python. You can add type hints to
your Python programs using the standard for type annotations introduced in
Python 3.5 (PEP 484), and use mypy to type check them statically. Find bugs in
your programs without even running them!
