Works for any module:

    $ perl -MLWP::UserAgent\ 999             
    LWP::UserAgent version 999 required--this is only version 5.833.

Well, almost any module:

    $ perl -MFile::Slurp\ 9999
    <hangs forever>

  mike@server:~$ perl -MLWP::UserAgent -e 'print $LWP::UserAgent::VERSION."\n"'
  5.835
  mike@server:~$

That works, too!

Even shorter, as -l appends \n to all prints:

    $ perl -MLWP::UserAgent -le 'print $LWP::UserAgent::VERSION'

Even shorter!

    $ M=LWP::UserAgent && perl -M$M -le "print \$$M::VERSION"

Even even shorter!

    $ M=LWP::UserAgent;perl -M$M -Esay\$$M::VERSION

This reminds me of that joke in which jokes have been reduced to numbers. It's nearly as obscure, too.

Did Gödel come up with that joke?
