That whole area relies on the fact that variables holding references to
final class instances are annotated with that class information, so
static method resolution can be made at compiletime rather than runtime.

In dynamic languages like Perl where there are no such annotations on
variables or other expressions, there's nothing you can use for that
kind of lookup, so it's just done at runtime.
