+(* This is a problem with the status of the type in LetIn: is it a
+   user-provided one or an inferred one? At the current time, the
+   kernel type-check the type in LetIn, which means that it must be
+   considered as user-provided when calling the kernel. However, in
+   practice it is inferred so that a universe refresh is needed to set
+   its status as "user-provided".

+   Especially, universe refreshing was not done for "set/pose" *)
