Once again, more niggle than desperate, but...

Why does CGI.pm not store a null value in param() if one is sent?

eg, 

my $q = new CGI;

my %conf = ... hash defined elsewhere

for ( $q->param() ) {
  $conf{$_} = $q->param($_);
}

All well and good, but if the field sent contains an empty value, it doesn't appear when looping through param().

So for each conf var that *can* be empty, I'm having to add: 

$conf{'var_name'} = $q->param('var_name');

[download]
explicitly.

Or am I missing some hidden feature of CGI.pm that covers this? It's just getting a little messy and umm i don't like that much...

.02 please :)
