Is this a bug of operator[] ?

In line 509 of tensor.h

/*!

• \brief get a element of dimension - 1
• \param idx index
• \return the result tensor
  */
  MSHADOW_XINLINE Tensor<Device, kSubdim, DType> operator[](index_t idx) const {
  return Tensor<Device, kSubdim, DType>(dptr_ + this->MemSize<1>() * idx,
  shape_.SubShape(), stride_, stream_);
  }

The template argument of MemSize seems wrong.
