What's expensive? The generation of all these overloads with the
preprocessor or the actual lookup with that many overloads?

If it's the former, I don't think that's very relevant. If you want to
use a tool like Phoenix, you probably should use a PCH version of it.

As a side note, more and more Boost libraries are making compilation
very slow, and it would be nice to integrate standardized PCH headers as
part of the Boost distribution, which would be automatically generated
at installation time.
