Vladimir, as you know I started Boos.Conversion as a more generic response to type-to-type conversion. ... I think the way Boost.Conversion is designed allows such overloading. It use a dummy parameter taking the type of the return type.
template typename boost::enable_if, TypeOut>::type convert_to(const StringIn& from, boost::dummy::type_tag const&);
template bool convert_to(const StringIn& from, boost::dummy::type_tag const&);
The library provides a convert_to function that adds the specific dummy parameter. I recognize this is tricky and that the overloading seems not natural from the user perspective but it works at least for the cases I have tested.
Vicente, Gordon, Thank you for the pointer, I had a quick look and indeed it seems to solve the specialization problem I was facing. Should we cancel/postpone this review and review Vicente's and mine together or something of that sort? If Vicente's is better as a starting point, it's fine by me. I am happy either way a s long as things are moving. V.
