- Error: In this with constraint, the new definition of t
-        does not match its original definition in the constrained signature:
-        Type declarations do not match:
-          type 'a t = 'a list = [] | (::) of 'a * 'a list
-        is not included in
-          type ('a : value_or_null) t = 'a list = [] | (::) of 'a * 'a list
-        The problem is in the kinds of a parameter:
-        The kind of 'a is value_or_null.
-        But the kind of 'a must be a subkind of value
-          because it instantiates an unannotated type parameter of t,
-          chosen to have kind value.
