We even have a keyword waiting for this: cond. On
consideration, I think I'd prefer instead generalizing
guards into deep guards (ie, at the very least,
user-defined calls available) everywhere.

An arbitrary call exiting in a guard would have to
convert to failure, just as guards work today. I'd
also suggest turning off side-effects while inside a
guard (even deep down in function calls), converting
attempted side-effects into exits.

(I guess the modest proposal above ought to be an EEP
too.)

Best,
Thomas
