(** Global options of the system. *)

(** WARNING: don't add new entries to this file!

    This file is own its way to deprecation in favor of a purely
   functional state, but meanwhile it will contain options that are
   truly global to the system such as [compat] or [debug]

    If you are thinking about adding a global flag, well, just
   don't. First of all, options make testins exponentially more
   expensive, due to the growth of flag combinations. So please make
   some effort in order for your idea to work in a configuration-free
   manner.

    If you absolutely must pass an option to your new system, then do
   so as a functional argument so flags are exposed to unit
   testing. Then, register such parameters with the proper
   state-handling mechanism of the top-level subsystem of Coq.

(** [with_modified_ref r nf f x] Temporarily modify a reference in the

    easy to fall in the typical problem with effects:

    with_modified_ref r nf f x y != with_modified_ref r nf (f x) y
