------------------------------------
Hi Kai, thanks for the suggestion. Sure, Will add the interoperatability test
case.

> Raw XOR coder is utilized in Reed-Solomon erasure coder in an optimization to
> recover only one erased block which is in most often case. It can also be
> used in HitchHiker coder. Therefore a native implementation of it would be
> deserved for performance gain.
