The logic needed to carry out promotions as specified in TR1 for the
std::complex function overloads is in boost/tr1/detail/math_overloads.hpp,
it could be used for a TR1 version of <cmath> as well when we get something
to put in it :-)
The logic is quite specific to the problem domain, and heavily dependent on
MPL though, so how generally applicable it would be I don't know.
John.
