How can I monkey-patch an instance method in Perl?

Question

I\'m trying to monkey-patch (duck-punch :-) a LWP::UserAgent instance, like so:

sub _user_agent_get_basic_credentials_patch {
  return ($usernam

Perl thinks you're trying to call the subroutine on the left of the assignment, which is why it's complaining. I think you may be able to whack the Perl symbol table directly (using *LWP::UserAgent::get_basic_credentials or something), but I lack the Perl-fu to correctly make that incantation.
