Doing something like this is bad practice, for a variety of reasons. Mostly because if someone adds a form field that you did not prepare for, it might affect a different part of the script. For example, if someone added a form field called "key" your script would die because it would try to set $key to the form value, which is also the loop iterator.

If you want to avoid calling $query->param() each and every time you want to access the form values, and I sympathize, you should try something like this:

use strict;
use CGI;

my $query = new CGI; # this will import the form values
my %vars = $query->Vars(); # this will "export" the form values

print "Name: ", $vars{name}, "\n";

...et cetera. See the CGI.pm manpage for more info about the Vars syntax.
