Similar question to the other one at the time of writing, but more specific: does anyone have a good, thorough introduction to the "async event loop" (sometimes known as "asyncio") pattern? By thorough I mean that it goes beyond a starter tutorial, into both examples of various supporting libraries and implementation details that matter for usage. I'm fine with a book, too.

There are popular libraries for it in both Python and Perl and I suspect I could make good use for it if I understood it.

Unfortunately, I've only ever used it in a cargo cult manner of sticking together functions until the error messages go away (yeah yeah, it was only for "throwaway" "prototypes") so I really don't understand how it all is meant to fit together.

I found this post to be amazing intro that shows you how to go from simple generators to async event loop.

This was very good! But true to what's common, it stops just as it gets really juicy!
