I believe some parts of pqs may be just what I need for some other purposes. I'm really interested in binary_operation. Code to infer return type of arithmetic operations is useful for other purposes, particularly since it appears to include std::complex.
As I've pointed out in the past, Joel de Guzman has posted what I believe to be the definitive implementation of this return type deduction facility. Lost my connection at the moment, but it should be findable through the usual boost archives. Look for a thread titled "limited form of type deduction" and http://tinyurl.com/ofqf.
