A hashing function on keys. It must be such that if two keys are equal according to
equal, then they have identical hash values as computed by
hash. Examples: suitable (
hash) pairs for arbitrary key types include
Hashtbl.hash) for comparing objects by structure (provided objects do not contain floats)
(fun x y -> compare x y = 0),
Hashtbl.hash) for comparing objects by structure and handling
Hashtbl.hash) for comparing objects by physical equality (e.g. for mutable or cyclic objects).

val create_scoped : scope:int -> string -> t
val create_local : string -> t
val create_persistent : string -> t
val create_predef : string -> t
Creates an identifier with the same name as the input, a fresh stamp, and no scope.
- raises [Fatal_error]
if called on a persistent / predef ident.
val name : t -> string
val unique_name : t -> string
val unique_toplevel_name : t -> string
val persistent : t -> bool
Compare identifiers by binding location. Two identifiers are the same either if they are both non-persistent and have been created by the same call to
create_*, or if they are both persistent and have the same name.
