Support entrypoint references in -m

Feature or enhancement

Proposal:

I'd like to adopt entry-points more at my company (we currently have top-level .py files that are often simple redirects to entry-point-style functions), but concern has been raised that there's no simple way for devs to mimic an entry-point invocation without installing their module, which is a hurdle to training. I'd like to extend -m to support entry-point syntax, i.e.

python -m importable.module:entrypoint_function [args...]

This should be roughly equivalent to adding this as a console_scripts entry-point, installing the module, and calling the entry-point from the bin dir:

• the function will be expected to look at sys.argv to see what's been passed in
• the first three elements in argv will be replaced with a single entry, so [args...] will be in argv[1:]

Has this already been discussed elsewhere?

Empieza por seguir el manejo de la línea de comandos de CPython para -m y compáralo con el comportamiento de los entry points de Packaging y de console_scripts descrito en la propuesta. Confirma cómo debería reescribirse sys.argv y qué ocurre con python -m importable.module:entrypoint_function [args...]; se considera terminado cuando la sintaxis invoca la función con los argumentos especificados y conserva el contrato de argv indicado.
