Judging from the several posts warning us that tracking run-time values
of modalities is a problem, I'd say no-one has found a way. (That
doesn't mean ya can't do it with a Quantum computer, IIUC the hype which
surrounds them. ;)
Oh, the pain of losing the blood, sweat, and tears which went into a
good hand-hewn tool. (I have 8 copies of my favourite, and my 300+ pages
of software survival notes. My memory is crumbling 20 years earlier than
Gene's, so I _need_ those notes to remain efficient.)
