Don't do this.  the precedence of || is too high.  your code attempts
to open a pipe, and if it can't, then it attempts to open "die..." and
starts throwing exceptions.


No, that is NOT what happens, it will NEVER attempt to open "die..." with or
without the parentheses.  The ONLY time it will attempt to open "die..." is if
there are no parentheses and the expression on the left hand side of the ||
operator evaluates to false.

open V4, '0' || die $!;

But even then it will NOT attempt to open "die..." because die() exits the
program!
