Version: 3.4 (development)

Description

As an example:

using Op = Eigen::VectorwiseOp<Eigen::Array<int, -1, -1, 0, -1, -1>, 0>;  
      
using T = Op::const_iterator; // subvector_stl_iterator<const ...>  
using U = decltype(std::declval<const Op&>().cbegin()); // subvector_stl_iterator<const ...>  
using V = decltype(std::cbegin(std::declval<const Op&>())); // subvector_stl_iterator<...>  

V should be the same as T, but isn't.
