This module is NOT meant to be directly imported! It has been designed such
that it can be bootstrapped into Python as the implementation of import. As
such it requires the injection of specific modules and attributes in order to
work. One should use importlib as the public-facing version of this module.

The .py file does not need to exist; this simply returns the path to the
.pyc file calculated as if the .py file were imported.
The 'optimization' parameter controls the presumed optimization level of
the bytecode file. If 'optimization' is not None, the string representation
of the argument is taken and verified to be alphanumeric (else ValueError
is raised).
The debug_override parameter is deprecated. If debug_override is not None,
a True value is the same as setting 'optimization' to the empty string
while a False value is equivalent to setting 'optimization' to '1'.
If sys.implementation.cache_tag is None then NotImplementedError is raised.
