This is really interesting. Thanks for writing this comment and sharing. Async is good for lots of IO work and managing independent tasks with low coupling. I am interested in task scheduling and asynchronous code I am interested in programming language development and parallelism and simultaneity without parallelism and cooperative and preemptive scheduling. As an experiment inspired by Protothreads (a C library for implementing cooperative multitasking with a switch statement) I recently implemented async/await in Java as a giant switch statement and a while loop. Providing that each coroutine only runs once, the amount of memory used shall not grow. The goal is to be stackless. I began writing a programming language that looks similar to JavaScript but targets an imaginary interpreter that is multithreaded. I hope to think of how to represent async await so that the high level language can target the interpreter. I need to think of the code I need to codegen to implement async/await. I played around with an C++ coroutines but someone told me that the approach I used is not C++20. Code is at https://GitHub.com/samsquire/multiversion-concurrency-control https://GitHub.com/samsquire/multiversion-concurrency-contro... The reconciliation loop idea sounds interesting.
