True, but once you learn that, if there are 4-5 sublibraries that also
have non-mnemonic names, it does start to look pretty confusing.

There are no such rules. There's nothing wrong with extending the
functionality of a library. Obviously, tacking the functionality of the
filesystem library onto Boost.Python wouldn't make sense, but I think
parsing and generation may be a bit more related than that ;-)
