So, do we *have* typeof registrations for the lambda and bind libraries?
Not AFAIK.
From the libraries currently in Boost, only spirit and xpressive had there types registered.
I would love to see lambda/bind to register their types, but this should be done by the library authors (or some volonteers intimately familiar with these libraries). Any help would be happily provided.
This is the usual dependency problem with new (hence optional) infrastructure. People using TYPEOF would ideally just #include <boost/bind.hpp> and have it all work. People _not_ using TYPEOF would ideally #include <boost/bind.hpp> and _not_ have it include any other headers that are of no interest to them. Unfortunately we can't have it both ways. Can we?
No, but I like the approach Eric used in xpressive: 1) have the types forward-declared; 2) register all the types in a separate file (something like bind_typeof.hpp). To use typeof then, one would have to include bind_typeof.hpp, and whichever headers from bind are needed. Regards, Arkadiy
