So, C++11 has been approved, and in the new standard library, there is:
template <typename T> std::pair<const T&, const T&> minmax ( const T& a, const T& b )
but in Boost, we've got: template <typename T> tuple< T const&, T const& > minmax(T const& a, T const& b) {
I can easily change boost minmax to return a pair instead of a 2-element tuple, but that's an interface change, and might break existing code.
On the other hand, giving them the same interface will make it easier for people to move to C++11's library functions.
Any opinions? ideas?
I could be wrong about this, but wouldn't that be problematic for C++03 std::pair, which (typically) barfs when instantiated with reference types? - Jeff
