Subject: gcc doesn't consider that    template<typename OtherDerived>
 TensorStridingOp& operator = (const OtherDerived& other) provides a valid
 assignment operator for the striding operation, and therefore refuses to
 compile code like: result.stride(foo) = source.stride(bar);

Added the explicit
   TensorStridingOp& operator = (const TensorStridingOp& other)

as a workaround to get the code to compile, and did the same in all the operations that can be used as lvalues.
