Web form element names automatically become script variable names and are
assigned their values...
use CGI 'param';
for $name (param()) {
$$name = param($name);
}
The double $$ is not a typo. Your question resulting in this solution has
reduced the script I'm working on, by about 2000 bytes, or about 3%. Thank
you.

Or if you prefer:
use CGI 'param';
$$_ = param($_) for (param());
An amazing little line, all parsing and creation of variables.
If you have multiples, you'll have to tweak it.
