Well there is a big difference too. Warnings Off is used to avoid the warnings
on unreferenced entity. But if later you start using it the compiler will
remain silent. Unreferenced said that the entity is unreferenced and if you
start using it you'll get a warnings. This will oblige you to revisit the code
and eventually remove the pragma.
