In fact do perhaps add examples to show that i and g each belong in their proper spot and not any other way:
$ perl -wle 'my $r=qr/w/; print for "Wow" =~ /$r/ig;' w (Could perhaps warn too. But yes not easy at run time.) $ perl -wle 'my $r=qr/w/i; print for "Wow" =~ /$r/ig;' W w $ perl -wle 'my $r=qr/w/g; print for "Wow" =~ /$r/ig;' (Gives error message, as expected.)
