Reasoning about and following the control flow of the proposed code hurts me inside. If Go adds function coloring via (e.g. python's async and/or yield concepts), I'm out, because I don't want to use this, much less encounter it in the form of a bug in some library. Java and C++ are largely inferior for my typical purposes, but at the end of the day they work fine and are stable in terms of direction, and don't tend to repeatedly bloat the language over pedantry. If you want top-notch performance, there's already C, C++, and Rust. I am not a fan of the function coloring shit in Python and Javascript. I don't want the kitchen sink!
