$self is perhaps initialized, but

no strict 'refs';
$self->{ &{$testcase} }

(I mean, the original, obfuscated version) is probably undef... But I'm no going to read this code any futher, frankly.

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. #11929 First ask yourself `How would I do this without a computer?'
