I think you may be looking for Doubly-nested deeply bound variable is undefined, which is the same thing, but without eval STR. From a response by chromatic there, this may be fixed in perl 5.10. I say "may" because you're using an eval-string which may cause it to be different from the bug reported, but, still, it might work :-)
