Good point. The explcit parentheses do indeed avoid the precedence problems that would come with: open CRITICALSERVERS, "$crout" || die "can't open file \n: $!"; Where the open function would take the second line as an alternative argument. For instance, I have no file named 'crout' in my filesystem, yet: Greetings! E:\d_drive\perlStuff>perl -w open CRITICALSERVERS, 'crout' || die "can't open file \n: $!"; close CRITICALSERVERS; ^Z does not produce an error message, because the die clause gets taken as an alternative. A stronger argument has to do with mindset. The || operator is an expression evaluation operator, appropriate to mathematical or paramathematical expressions. The context really calls for a flow-control operator, or.
