No, they're not implemented at all yet. They're kinda less interesting
without laziness. OTOH, I guess they maybe ain't so much lazy
themselves, as the things (like grep) that they pass data onto are, so
it may not be entirely pointless to get a first cut of them in soonish
(and it doesn't look too hard to get the basics in). Full support, in
all its multi-threaded lazy transactional glory, will probably be quite
a while though.
Thanks,
