       The  output signature of the functor Ephemeron.K1.Make and Ephemeron.K2.Make .  These hash
       tables are weak in the keys. If all the keys of a binding are alive the binding  is  kept,
       but if one of the keys of the binding is dead then the binding is removed.

       ===  Propose  the same interface as usual hash table. However since the bindings are weak,
       even if mem h k is true, a subsequent find h k may raise  Not_found  because  the  garbage
       collector  can  run  between  the two.  Moreover, the table shouldn't be modified during a
       call to iter.  Use filter_map_inplace in this case. ===

       include Hashtbl.S

       val clean : 'a t -> unit

       remove all dead bindings. Done automatically during automatic resizing.

       val stats_alive : 'a t -> Hashtbl.statistics

       same as Hashtbl.SeededS.stats but only count the alive bindings
