The code that you can use in [perl] and [calc] blocks is different from
what is used in the core. This is because [perl] blocks are subject to
safe hole restrictions. In your code above you would use %$CGI instead
of %CGI::values:
while (my ($key, $value) = each %$CGI) {
...
}
For a list of perl variables you can use in [perl] and [calc] blocks and
their equivalents in the core see:
