[HoustonTx.pm] Interactive Perl trick

[houston at mail.pm.org]

I had to solve a problem very quickly this morning and used a trick
that I've found handy many times in the past. Some of you may find
it interesting.

  perl -de0

This executes the script '0' in the perl debugger. By itself, that's
not real exciting, but it leaves you in an environment where you can
execute Perl code interactively.

A 'q' by itself will exit the debugger. The debugger is actually
good for other things, but over the years I've most often used it
this way.
