It's worth pointing out that your example sub could be replaced by my %INPUT = $CGI->Vars; or $INPUT = $CGI->Vars;
Okay, time to bring something up here... I was earlier (a year ago or so here at perlmonks) in a discussion over using a for() loop vs. using CGI::Vars. IIRC, the general decision was to stick with a loop to copy the values into a hash, because of some compatability issues with the fact that CGI::Vars looks back on the old cgi-lib.pl library. Perhaps CGI.pm has been updated since then? Anyone have any input on this (again, after such a long time?)
