Though there's a big caveat with missing modules -- if the user does a #include and Boost.Optional wasn't installed, they might get an older Boost.Optional from the OS packages rather than an error, which is probably wrong (because mixing versions unintentionally is bad).

This does happen in practice, and yes, it's bad.
