[Python-ideas] Syntax to import modules before running command from the command line

Currently invoking `python -c "some;separated;set of commands;"` will,
if you need to use any library functions, require one or more import
somelib; sections in the execution string. This results in rather
complex "one liners".
On the other hand `python -m somelib` will load somelib and attempt to
execute its `__main__()` or give an error if there isn't one.
What I would like to suggest is a mechanism to pre-load libraries before
evaluating the -c option as this would allow the use of code from
libraries that don't have a `__main__` function, or those that do but it
doesn't do what you want.
Since -m for module is already taken I would suggest one of:
-p for pre-load module
-M for load module without attempting to execute `module.__main__()`
and without defining "__main__" in the load context or
-l for library
with the last two having the advantage of appearing next to -m in the
This would change, (for a trivial example):
`python -c"import numpy;print(numpy.pi);"`
`python -M numpy -c"print(numpy.pi);"`
