The value of the trait is the index of T within the specified list of Types (first type as index 0). The first StartFrom Types are ignored, but still counted. The match is exact, as in std::is_same. If none of the Types exactly matches T, the trait value will be the number of types (i.e. sizeof...(Types)), which is the index after the last of the types.

This is a integral trait (type std::size_t): use it as std::integer_constant.
