Fixing dual imports of the main module
--------------------------------------
Two simple changes are proposed to fix this problem:
1. In ``runpy``, modify the implementation of the ``-m`` switch handling to
install the specified module in ``sys.modules`` under both its real name
and the name ``__main__``. (Currently it is only installed as the latter)
2. When directly executing a module, install it in ``sys.modules`` under
``os.path.splitext(os.path.basename(__file__))[0]`` as well as under
``__main__``.
With the main module also stored under its "real" name, imports will pick it
up from the ``sys.modules`` cache rather than reimporting it under a new name.

+1 on both of these.
I don't see any major problems with these. Any minor issues can be worked out.
I suggest separating these two items out into their own PEP, and doing them
first.
Cheers,
Ron
