GoKawiilEssay Argues Function Coloring Isn't the Same as Ordinary Parameters
A programming-theory essay pushes back on the claim that any threaded function argument, such as Go's context.Context, qualifies as a 'function color' like async/await. The author argues that if every parameter counted as a color, the concept wouldn't have needed inventing decades after functions themselves existed, and proposes analyzing coloring instead as a question of how a change to one function propagates through the call graph to its callers.
