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.
Something to consider here is how this will interact with Python files
which are _not_ modules. I'm a little uneasy about having
sys.modules["trial"] refer to the module defined by /usr/bin/trial.
