could be considered an advanced option rather than the default, especially
since the aim (AIUI) of the all-users install is to pretend that Python was
shipped with the OS. (I'd kind of like to take that further by splitting
things more sensibly between Program Files, Common Files and System32, but
there's very little gain from that and much MUCH pain as long as people are
still expecting C:\PythonXY installs…)

points, specifically the console_scripts and ui_scripts (or whatever it’s
called) entrypoints and then give Python something like -m, but which
executes a specific entry point name instead of a module name (or maybe -m
can fall back to looking at entry points? I don’t know).

While I like the idea of offering something more "built in" in this space,
my initial inclination is to prefer extending "-m" to accept the
"module.name:function.name" format to let you invoke entry points by the
name of the target function (Possible API name: runpy.run_cli_function),
and then add a "runpy.call" that can be used to call an arbitrary function
with positional and keyword string arguments based on sys.argv and
(optionally?) print the repr of the result.

It wouldn't be a universal panacea (and would need a PEP to work out the
exact UX details), but would likely make quite a few libraries more command
line accessible without needing to modify them.

Cheers,
Nick.
