  • The distinction between the two is very slim: || has a higher precedence, while or has a very low precedence. So choose just based on what kind of precedence you want. For example:

    print "do" || "die";

    evaluates the whole RHS as an expression for print, while

    print "do" or die;

    evaluates print "do" and will die() only when print fails for example when printing to a closed filehandle, of to a full disk.

    I just hope I seem to make sense.

  • I have never been sure when writing code before now (like in a 'die' statement) whether to use || or the OR operator.

    Of those two, always the first, as the OR operator no longer exists (it was made lower case).
