$x should not disappear outside the scope of foo. my $x if undef; means that $x is not local; the my, though noted at compile time (mainly to prevent strict complaints), does not actually produce a scoping effect until run-time (if I understand the perldocs correctly). Therefore, the my $x is never evaluated for scoping purposes, since undef is always false.

  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
