Bug description
Hashtbl module should have a function, that give back a list of all keys of a table.
Hashtbl.keys should report every key only once!
I coded this very often myself.
I think other people also do.
(In contrary a Hashtbl.values might not be that necessary, because the Hashtbl.keys-reult plus some list stuff, or the Hashtbl.fold function can then be used. But Hashtbl.keys needs more coding effort.)
