 <hr>
 
+18/6 (AR)
+Added a warning for clashing constants. A constant coming from multiple opened modules
+was interpreted as "the first" found by the compiler, which was a source of difficult
+errors. Clashing is officially forbidden, but we chose to give a warning instead of
+raising an error to begin with (in version 2.8).

+30/1/2007 (AR)
+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.
