Have you tried it yet?

Unfortunately I have the reverse of your experience. Parsing with a
big switch and implementing my own DFA for incremental HTTP parsing is
so ugly and unintuitive that I've had to rely too much on trial and
error while doing it. I long for the day when I can just define a
restartable Boost.Spirit based composed parser and not have to worry
about the parsing details -- I really want to define my parsers now in
a declarative way that Boost.Spirit across all the versions I've used
(Classic and v2.x), and hopefully that won't be too far in the future.

Just my $0.02 worth.
