>> 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:

> In the function color analogy, what this means is that all functions are red

and

> while Go does not distinguish between async and sync functions

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

I was not looking to disagree with your point, I only wanted to make additional commentary. Sorry if my comment came across the wrong way.

I do think "There are no function colors in Go in the way being discussed," versus "all functions [in Go] are red" are two slightly different ways of formulating the same set of facts, and the distinction between them is insightful, so that was what I wanted to touch upon. Namely, I wanted to point out that there is an "implicit" color within the programming language itself.
