taking a look at the -M syntax in perlrun, a cute thing you could do is to implement (or override) import() in your package, and respond to triggers passed in:

package DoIt;

sub import {
    &run if( $_[0] eq 'run' );
}

the following commandline:

perl -MDoIt=run,arg1,arg2

will call the DoIt::run sub with @_ set to qw(run arg1 arg2).
