(** This modules implements basic manipulations of errors for use
throughout Coq's code. *)
(** [register_handler h] registers [h] as a handler.
When an expression is printed with [print e], it
goes through all registered handles (the most
recent first) until a handle deals with it.
Handles signal that they don't deal with some exception
by raisine [Unhandled].
Handles can raise exceptions themselves, in which
case, the exception is passed to the handles which
were registered before. *)
