Note to self: we stopped while we were talking about whether we need `is_trivially_copyable` in `small_buffer` (which we pedantically need):

```
template <class _Tp, class _Decayed = decay_t<_Tp>>
  static constexpr bool __fits_in_buffer =
      is_trivially_move_constructible_v<_Decayed> && is_trivially_destructible_v<_Decayed> &&
      sizeof(_Decayed) <= _BufferSize && alignof(_Decayed) <= _BufferAlignment;
```
