reviewing my work for binary_operation with regard to complex. I think that
the following covers it as far as the definition goes. Not tested thoroughly
but appears to cover all including inbuilts etc... (Yes that means I can
remove a lot of unnecessary specialisations from pqs/complex.. :-) ). Should
also bring in functors as described previously
