Trace.DelayedDelayed reporters.
May be useful for heisen bugs that vanish on printing.
type trace := tval make : unit -> tmake () is a new delayed reporter. You need to install it with reporter and set_reporter.
val clear : t -> unitclear d clears traces from d.
val pp : Stdlib.Format.formatter -> t -> unitpp formats the traces kept by d.
val prerr : t -> unitprerr formats the traces kept by d on stderr.
