I think disallowing short option altogether is not a bad convention. With only `-long` and `-long=xxx`, my command line parsing is simply

    foreach a in arglist
        if a=~/^-(\w+)(?:=(.+))?/
            $opts{$1} = $2;
        else
            push @pos_list, $a 

There is no need for the dependency and complexity of `getopt` library.

And for the user side, no more cryptic ninja arts. The only trick user need to learn is the shell alias and functions.
