Hi, This is the second time that I have found the following function useful when playing with variants of Optional library:
template <typename T, typename U> typename std::enable_if<std::is_convertible<U, T>::value, T>::type convert(U && u) { return std::forward<U>(u); }
It performs an implicit conversion from U to T, but you can call it explicitly.
Isn't it what implicit_cast does? See boost/implicit_cast.hpp.
