In the Perl world we never treat modules as scripts; they are separate concepts written separately and installed in separate locations.  There is no feature of perl similar to the Pythonish -m stuff.

It might look similar but it's not.

If it was similar 'python -mfoo' would be a shortcut for 'python -c "import foo"' and 'python -Mfoo' would be a shortcut for 'python -c "from foo import *".  It would also have to be possible to repeat the -c option.  Then we could have written the Perl-esque:

    python -Mdistutils2.depgraph -c "main()"

There is no way to do something similar to 'python -mfoo ...' from perl.  The closest thing I could think of would be 'perl $(perldoc -l foo) ...', assuming a bash-like shell.
