val find_value_index : Ident.t -> t -> int option

The find_*_index functions computes a "namespaced" De Bruijn index of an identifier in a given environment. In other words, it returns how many times an identifier has been shadowed by a more recent identifiers with the same name in a given environment. Those functions return None when the identifier is not bound in the environment. This behavior is there to facilitate the detection of inconsistent printing environment, but should disappear in the long term.
