The question is a bit muddy with the terminology, but I can guess what you're aiming at.

As of the versions 5.10 .. 5.16, declaring no version with use enables none of the feature. You still get to use the smart-match and defined-or operators.

In conclusion, it feels like old Perl (5.6 .. 5.8) with extra operators.
