+(** Namespace of module vs. namescope of definitions/constructors/...
+
+As noticed by A. Appel in bug #2603, module names and definition
+names used to be in the same namespace. But conflict with names
+of constructors (or 2nd mutual inductive...) used to not be checked
+enough, leading to stange situations.
+
+- In 8.3pl3 we introduced checks that forbid uniformly the following
+ situations.
+
+- For 8.4 we finally managed to make module names and other names
+ live in two separate namespace, hence allowing all of the following
+ situations.

+Declare Module E : T.
+End L.

+Module M1 : L with Module E:=K.
+Module E := K.
+Inductive t := E. (* Used to be accepted, but End M1 below was failing *)

+Inductive t := E.
