I dislike all of Ruby's magic, metaprogramming, and that it's almost impossible to statically analyze, however I have come to appreciate how nice it is in Ruby not to have functions with 'color' like this article mentions. I certainly hope TC39 can find a way to bake in similar async-agnostic syntax to Javascript. I'm not sure if it's possible with syntax alone, or if it would require a new language.

Consider yourself fortunate to have (forgive the assumption!) never worked in a ruby codebase that uses eventmachine or promise.rb. It’s less common than in some other languages but ruby is perfectly capable of a callback/promise-based model for performing async io or query batching, for example. And it creates exactly the “function color” problem that this article describes.
