Subject: [PATCH] put_inductive_definition implemented and exposed. It is a
very UNSAFE solution to the problem of computing inner-types of
non-debrujined mutual inductive types (whose constructors referes to the
not-yet-defined inductive type block): you can use this function to add the
block to the environment; then you compute the inner-types; and finally you
save the object and register it to the getter.
