Hmm, for `vector` and `deque`, we define a temporary variable, check that sizes
match and then use range-and-a-half `equal`:
const typename vector<_Tp1, _Allocator1>::size_type __sz = __x.size();
return __sz == __y.size() && _VSTD::equal(__x.begin(), __x.end(),
__y.begin());
For `list` we check that sizes match and then use range-and-a-half `equal`, but
don't use a temporary variable:
return __x.size() == __y.size() && _VSTD::equal(__x.begin(), __x.end(),
__y.begin());
For `array` we check that sizes match and then use dual-range `equal`:
if (_Size1 != _Size2)
return false;
return _VSTD::equal(__x.begin(), __x.end(), __y.begin(), __y.end());
Is there a subtle reason for this inconsistency that I'm not seeing?
