You also moved some methods and it complicate the review :(

I know,,, i made this super huge pr,,,,,, it just keep growing while i was trying to make it work....... have being working on this for 15 hours without resting......

I tried my best to make it easier for reviewing, and avoided changes to the compile result.....

BUT, there is still a case that will change the artifact,,, which is I added exception message while calling throw for nemuric methods.

this will not be merged.
