Not only do I want to see this put forth for review, but I'd also like to
see its review fast-tracked, since it's a target for standardization
currently being examined by LEWG.  There are a few of us in LEWG that want
to see essentially *all* novel library submissions do through Boost or
another widely-used library.  Mostly you can find these people on this
list. :)

This is why Boost was initially created, after all.  Whether it passes
review without change, gets rejected, or anything in between, the process
will be very informative to LEWG.
