I am sympathetic to your idea of making an FFT which works in an arbitrary field, but 
according to the C++ ISO spec, §26.2/2:
The effect of instantiating the template complex for any type other than float, double or long double is unspecified.

So we are not going to be able to define a finite field F[p] and plug it into std::complex<>. 

Should not then the focus be on the types that Boost.Multiprecision supports, and especially its own complex types?
