Yesterday I develop solution (may be not first) to well known problem with cgi scripts if/else selector:
$actions = $CGI->param ('action');
$to_do = new INVOICES();
if ($actions eq 'delayedinv') { $to_do->delayedinv() }
elsif ($actions eq 'del_inv') { $to_do->del_inv() }
elsif ($actions eq 'payed' ) { $to_do->payed () }
elsif ($actions eq 'stats' ) { $to_do->stats () }
... skip ...
else { $to_do->defscreen()}

We all know solution for this from Perl Cookbook with a hashtable.

so my solution is ...
$actions = $CGI->param ('action');
$to_do = new INVOICES();
eval {$to_do->$actions} || defscreen();

also we can implement with regexp a filter to prevent access to private methods.

Any emotions, opinions, points of view?
