// A value of type gtl::optional<T> holds either a value of T or an
// "empty" value. When it holds a value of T, it stores it as a direct
// subobject, so sizeof(optional<T>) is approximately sizeof(T)+1. The interface
// is based on the upcoming std::optional<T>, and gtl::optional<T> is
// designed to be cheaply drop-in replaceable by std::optional<T>, once it is
// rolled out.
//
// This implementation is based on the specification in the latest draft as of
// 2017-01-05, section 20.6.
//
// Differences between gtl::optional<T> and std::optional<T> include:
// - constexpr not used for nonconst member functions.
// (dependency on some differences between C++11 and C++14.)
// - nullopt and in_place are not constexpr. We need the inline variable
// support in C++17 for external linkage.
// - optional::swap() and swap() relies on std::is_(nothrow_)swappable
// which is introduced in C++17. So we assume is_swappable is always true
// and is_nothrow_swappable is same as std::is_trivial.
// - make_optional cannot be constexpr due to absence of guaranteed copy
// elision.
