As far as my understanding goes, yes, but I think it'd be wise to wait for
one (or maybe two) release cycle(s) before advertising it as official.
Just before release: I just realised that "end" doesn't work for strings
(neither does the [k:] syntax anyway). Allin, would this be difficult to
add? Not a priority of course, I'm perfectly happy with putting this off
for a while.
