One idea from PEP 451 was to add a "target" parameter to runpy.run_path and runpy.run_module to allow them to support execution in an existing module namespace (like __main__). This missed the feature freeze deadline for 3.4, but can be added in 3.5.

Implementing this is actually likely to require non-trivial restructuring of the runpy internals. contextlib.ExitStack may prove useful in making it easier to programmatically select amongst different context managers. The __mp_main__ helpers in multiprocessing should also be able to take advantage of this once it is available, and it may prove useful in finally providing -m analogues for pdb etc that play nice when an exception occurs (see issue 9325).

Hey ncoghlan, Does this issue makes sense to be worked on for Python 3.7?

See issue 21862 and issue 9325 as potential use cases for this feature. While it looks like issue 21862 (-m switch support in cProfile) can be implemented just fine without it, this feature will be needed for the modules that execute the given scripts directly in __main__.__dict__ (e.g. pdb).

issue 19978 also needs this.
