I'm trying to make a generalised form-creation script, with a certain look and feel, that I can re-use for various things, using CGI.pm.

Here's an example: 

%fields = (
  'name',        'textfield',
  'email',       'textfield',
  'site name',   'textfield', 
  'description', 'textfield',
  'comments',    'textarea'
);



foreach $key (keys(%fields)) {
$thisrow = td({-align=>right,-valign=>TOP},$key);
if($fields{$key} eq 'textfield'){
   $thisrow .= td({-align=>left,-valign=>TOP},
   textfield(-name=>$key,-size=>50,-maxlength=>80)
   );
}
if($fields{$key} eq 'textarea'){
   $thisrow .= td({-align=>left,-valign=>TOP},
   textarea(-name=>$key,-cols=>50,-rows=>10)
   );
}
push(@rows,$thisrow);
}

print table({-border=>1,-width=>'50%'},
            Tr(\@rows)
           );

But as you can see, it's not going to be very generalised, because I'm having to test for the type of field every time: if it's a textfield, do the textfield thing, if it's a textarea, do something else.

What I can't figure out is how to do this: 


   $thisrow .= td({-align=>left,-valign=>TOP},
   $fields{$key}(-name=>$key)); # make a textfield
                                # because the value is
                                # 'textfield' - DWIM!

i.e. call the particular CGI.pm sub using the value, which is the name of that sub.

Any help greatly appreciated...
