Subject: [boost] Phoenix: is there a Phoenix expression trait?

I'm adding a convert_to Phoenix like functor to Boost.Conversion.
I would like to use the same name, i.e. convert_to, but the overloads conflict. I would like to use sfinae to choose the correct overloading between
typename expression::convert_to, U>::type const
convert_to(U const& u);
Target convert_to(Source const& from, boost::dummy::base_tag const& p=boost::dummy::base_tag())
Is there a trait that can be used to detect if the parameter is a Phoenix expression?
BTW, I have just based my implementation on the one for static_cast, that uses the detail
Could someone explain me why this is needed?
Could this detail be moved to the user interface?
