Yes, but I do not recommend this "rename" method for wide use. Some 
decades ago, in an Ada 83 project which thus did not allow "use type", 
we had several bugs where copy-paste sloppiness resulted in (for 
example) some "-" operator renaming a "+" operator, with "amusing" results.

I believe the risk of such bugs was a major reason for the introduction 
of "use type" in Ada.
