>> Go language praised in the article still has red and blue functions

This is my principle point of disagreement with the OP comment in this thread. Your response is either not meant for me, or is meant to agree with me, but I'm really not sure but you write:

and

Which was my point. Go does not have the function color problem (around sync/async) because it does not color its functions that way.
