From perldelta on 5.10.0:

  Deprecated use of my() in false conditional
      A new deprecation warning, *Deprecated use of my() in false
      conditional*, has been added, to warn against the use of the dubious
      and deprecated construct

          my $x if 0;

I'd always heard not to initialize my variables in a conditional statement.
