Unfortunately for you, it so much easier on the coder to
add:
use CGI qw(param);
than it is to cut can copy this into a script, or make turn
it into a module. We are big on code re-use at the
Monastery. People constantly complain that CGI.pm is too
bloated, but it rarely really ever is. Besides, what happens
when you suddenly need to parse upload fields?
Even though you do handle multiple fields, your code is
going to break on a string like
foo=one%20field&foo=two%2Cfield which should only
yield two elements for foo, not three. For that matter, i
prefer to deal with a list instead of being handed a
delimited string that i have to split myself.
UPDATE: observe how CGI.pm handles this:
perl -MCGI=param -le"print for param(foo)" "foo=bar&foo=one%2Cfield"
