$self is perhaps initialized, but 
no strict 'refs';
$self->{ &{$testcase} }

    That was my original thought, and then I saw Use of uninitialized value $self in concatenation (.) or string That's why I think my $self = shift or confess '$self undef'; is probably the best bet. I should point out that the $self that is uninitialized may not be the $self in the grotesque expression above.
