I said I'd make a patch which follows his suggestion, but that I'd try to
convince him to accept the first patch.  I'll reiterate, I think it would
be more surprising to have boost::result_of not work with
compiler-supported lambdas than to have it correctly deduce results that
would have been erroneous using TR1.  Even though VC10's std::result_of
didn't work with them either (for example).

Thanks,
Nate
