-"""For neatly implementing static typing in packaging.
-
-`mypy` - the static type analysis tool we use - uses the `typing` module, which
-provides core functionality fundamental to mypy's functioning.
-
-Generally, `typing` would be imported at runtime and used in that fashion -
-it acts as a no-op at runtime and does not have any run-time overhead by
-design.
-
-As it turns out, `typing` is not vendorable - it uses separate sources for
-Python 2/Python 3. Thus, this codebase can not expect it to be present.
-To work around this, mypy allows the typing import to be behind a False-y
-optional to prevent it from running at runtime and type-comments can be used
-to remove the need for the types to be accessible directly during runtime.
-
-This module provides the False-y guard in a nicely named fashion so that a
-curious maintainer can reach here to read this.
-
-In packaging, all static-typing related imports should be guarded as follows:
-
-    from packaging._typing import TYPE_CHECKING
-
-    if TYPE_CHECKING:
-        from typing import ...
-
-Ref: https://github.com/python/mypy/issues/3216

-# The TYPE_CHECKING constant defined by the typing module is False at runtime
-# but True while type checking.
-if False:  # pragma: no cover

-else:
-    TYPE_CHECKING = False
-
-# typing's cast syntax requires calling typing.cast at runtime, but we don't
-# want to import typing at runtime. Here, we inform the type checkers that
-# we're importing `typing.cast` as `cast` and re-implement typing.cast's
-# runtime behavior in a block that is ignored by type checkers.
