Hi Thomas

I'm acutely aware how easily and painlessly Phoenix would solve my problems,
but sadly it
won't be an option for me for quite a while in production code.

In the meantime your suggestion 1 nearly works - I found I needed to write

bind(static_cast<const X &(*)(const X &, const X &)>(&std::max), ....)

Thanks for your help.
