Calculate values on demand

Unlike the tie-based DataLazy, this module operates on values, not variables. Therefore, assigning into $dv and $lv above will simply replace the value, instead of triggering a STORE method call.

Also, thanks to the overload-based implementation, this module is about 2x faster than DataLazy.
