My research is showing me, that the opposite is correct: The "indefinite
extent" functions' behaviour is simpler/more natural/more useful for a user,
than the behaviour of its "definite extent" counterpart (that's probably the
reason, why Carl introduced "indefinite extent" to Rebol), and, moreover,
there *is* a way, how to make such functions faster, than the Rebol
functions are nowadays.
