RTTI has a non-trivial cost, so some users disable this feature. In
particular, RTTI tends to make binaries larger, since compilers
produce additional functions that are needed to support the RTTI
facilities. In any case, Boost.Function shouldn't try to dictate what
language features users use, and it's perfectly acceptable for
Boost.Function to provide less functionally when RTTI is not
