Another way to easily access form parameters when using CGI.pm is to use import_names.

For example:

....
use CGI;
my $q = new CGI;
$q->import_names('Q');
....
inerror("we couldn't find $Q::home, please check path");

From "perldoc CGI":

       IMPORTING ALL PARAMETERS INTO A NAMESPACE:

          $query->import_names('R');

       This creates a series of variables in the 'R' namespace.
       For example, $R::foo, @R:foo.  For keyword lists, a vari­
       able @R::keywords will appear.  If no namespace is given,
       this method will assume 'Q'.  WARNING:  don't import any­
       thing into 'main'; this is a major security risk!!!!

       In older versions, this method was called import().  As of
       version 2.20, this name has been removed completely to
       avoid conflict with the built-in Perl module import opera­
       tor.
