Perhaps I'm missing something but...
"how requires_login/requires_role would store the fact that the
provided sub requires auth"
Simple implementation:
# given has_role is calculable
sub requires_role { 
        my ($role, $code, $handle_exception) = @_;
        return sub {
                if (has_role($role)){
                        $code->(@_);
                }
                else{
                        if (defined $handle_exception){
                                $handle_exception->($role, @_)
                        }
                        else {
                                default_403_no_role($role, @_)
                        }
                }
        }
}
Ah, yes - that's pretty clever.  I think like that approach - it's
simple and solid.

Thanks!
