+Added a warning for clashing constants. A constant coming from multiple opened modules

+raising an error to begin with (in version 2.8).

+Semantics of variants fixed for complex types. Officially, it was only
+defined for basic types (Str and parameters). When used for records, results were
+multiplicative, which was nor usable. But now variants should work for any type.
