Which part of "once its defined" did you not understand?

What a mess. And I didn't realise perl allowed variables of different types
to have the same name! Insanity! Another reason never to use it again.

Meanwhile in awk: { print }

I understand Perl vies with C++ as the most syntactically messy language
in common use. Unfortunately I have to use the latter, I don't have to use
the former.
