Also, a colored functions approach for php would make a future thread-based concurrency approach completely non-viable, because it would require marking ALL functions (not just IO-bound functions, CPU-bound ones as well) as async and forcing the use of await for ALL function calls, just to be able to sometimes use some functions in parallel (in separate threads). Colored functions completely preclude a possible future thread-based implementation of concurrency. Regards, Daniil Gentili.
