Automatically reporting errors for raised exceptions

val register_error_of_exn : (exn -> Error.t option) -> unit

Each compiler module which defines a custom type of exception which can surface as a user-visible error should register a "printer" for this exception using register_error_of_exn. The result of the printer is an error value containing a location, a message, and optionally sub-messages (each of them being located as well).

val raise_errorf : ?loc:t -> ('a, Format.formatter, unit, 'b) format4 -> 'a

val report_exception : Format.formatter -> exn -> unit

Reraise the exception if it is unknown.

exception Error of Error.t

Raising Error e signals an error e; the exception will be caught and the error will be printed.
