(** The following provides a level of abstraction for the kind of environment used for type inference (so-called pretyping); in particular: - it supports that term variables can be interpreted as Ltac variables pointing to the effective expected name - it incrementally and lazily computes the renaming of rel variables used to build purely-named evar contexts

(** [hide_variable env id] tells to hide the binding of [id] in the ltac environment part of [env]. It is useful e.g. for the dual status of [y] as term and binder. This is the case of [match y return p with ... end] which implicitly denotes [match z as z return p with ... end] when [y] is bound to a variable [z] and [match t as y return p with ... end] when [y] is bound to a non-variable term [t]. In the latter case, the
binding of [y] to [t] should be hidden in [p]. *)
