  • 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.
