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.
