This in itself isn't a bad thing. When I'm porting code, I try to start with a proven code-base and port from there, while iterating the code to make it more idiomatic (e.g. "case OP_LOADK" is not idiomatic Go). The problem is, if the author has based their code on this library, they seem not to have credited it (At least, I couldn't find it on my cursory look at the file headers).
