in reply to How to use require...

Ok, autouse is of course ver elegant. I'd probably used something like the following, to save subroutne names.

my %actions = ( 'login' => sub { require Login; do_login(); }, ... );

But anyway, there's a slight problem about your code. Imagine somehow the "action" parameter is filled with nonsense, which should happen at least when you want to test your script. You'll get:

Use of uninitialized value in subroutine entry at ... Can't use string ("") as a subroutine ref while "strict refs" in use a +t .....

Simply because $query might contain "foo" (which does not exist in %actions). Just add a check to your code:

$query = 'default' unless exists $actions{ $query };
