And the official line from perlsyn:
NOTE: The behaviour of a "my", "state", or "our" modified with a statement
modifier conditional or loop construct (for example, "my $x if ...") is
undefined. The value of the "my" variable may be "undef", any previously
assigned value, or possibly anything else. Don't rely on it. Future
versions of perl might do something different from the version of perl you
try it out on. Here be dragons.
