val declare_instance : ?⁠warn:bool -> Environ.env -> Evd.evar_map -> Typeclasses.hint_info option -> Goptions.option_locality -> Names.GlobRef.t -> unit: Declares the given global reference as an instance of its type. Does nothing — or emit a “not-a-class” warning if the warn argument is set — when said type is not a registered type class.
