You might consider using the lower precedence "or" especially for error checking. The double pipe version is more useful for when you want to do short-circuit evaluation in conditional expressions.

opendir DIR, '/'
  or die "Failure opening dir /: $!";

Stylistically I find this much easier to read and you don't have to worry about precedence as 'or' and 'xor' are as low as you can get on the chart ;).
