in reply to hash n' params

When you're initialising a hash that contains a group of settings, you can put them together like this:

my %exec = ( html2ps => '/usr/bin/html2ps', ps2pdf => '/usr/bin/ps2pdf', html2text => '~/perl/html2text' );
which IMHO looks nicer. You're explicitly allowed to use barewords on the left hand side of a =>, even if "use strict" is in force.

    Warning. A bug I recently learned about:
    use strict; my %trial_hash = ( foo => "bar", );
    does not run properly in a Perl program, but does if you use eval. So while I use the "big arrow", you should put it on the same line as the key, not the value.
