in reply to Use modules with an import list on the command line

Might also point out that the specifics are documented in this section of perlrun:

    -m[-]module
    -M[-]module
    -M[-]'module ...'
    -[mM][-]module=arg[,arg]...
      -mmodule executes `use' module `();' before executing your program.

      -Mmodule executes `use' module `;' before executing your program. You can use quotes to add extra code after the module name, e.g., `'-Mmodule qw(foo bar)''.

      If the first character after the -M or -m is a dash (`-') then the 'use' is replaced with 'no'.

      A little builtin syntactic sugar means you can also say -mmodule=foo,bar or -Mmodule=foo,bar as a shortcut for `'-Mmodule qw(foo bar)''. This avoids the need to use quotes when importing symbols. The actual code generated by -Mmodule=foo,bar is `use module split(/,/,q{foo,bar})'. Note that the `=' form removes the distinction between -m and -M.
