I see this comment at the beginning of streams.ml:
(* The fields of type t are not mutable to preserve polymorphism of
the empty stream. This is type safe because the empty stream is never
patched. *)
Is this still true? I can easily imagine that it used to be true if
and when OCAML had weak type variables, but it doesn't anymore.
If it isn't true any more, then I think it would be possible to make a version
of streams that's as fast and functional as what's there now, and it
would allow consing streams to interoperate properly with streams
derived from functions or channels.
