No.  Use or for flow control and you won't find yourself fighting
against Perl.  Reserve use of || for non-flow control.  (For the
pedants, I define flow control as the operation being in void context
or an argument to a flow control and/or operation.)

Or always use parens with builtins.  Some people advocate that anyway,
but I don't care for it.

And Larry, not p5p, AFAIK.
