Steve forgot about PHP SDK :D TBH in case of PHP, it seems that the whole concept is built on using Generators as coroutines (this approach suffers from the red blue function problem), what people used to do until the 8th version of PHP. Since 8.1 Fibers were introduced, and it is such a releif to use AMPHP set of libraries that doesn't suffer from Generator signatures anymore, so that one could just write the function with just normal signature and it's absolutely not necessary to think about async workflows and non-blocking IO where you don't want to deal with it directly.
