//! The allocator_arg_t struct is an empty structure type used as a unique type to

static const allocator_arg_t allocator_arg = allocator_arg_t();
//! <b>Remark</b>: if a specialization is derived from true_type, indicates that T may be constructed
//! with an allocator as its last constructor argument. Ideally, all constructors of T (including the
//! copy and move constructors) should have a variant that accepts a final argument of
