Holding refs to subroutines seems like a perfectly good way to do private methods:

package Foo; . . . my $fiddle = sub { my $self = shift; return map { scalar reverse $_ } @_; }; sub wonk { my $self = shift; $self->$fiddle(@_); } package Bar; sub wonk { my $self = shift; $self->$fiddle(@_); # runtime error }

The real problem is that Perl doesn't have a good way of denoting protected methods or attributes. I don't consider litering your code with $obj->isa( . . . ) or die; to be a good way.

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.
