Nonsense, there's AnyEvent, EV, IO::Async, Mojo::IOLoop. If you need parallelism, yes, you'd better use Go or something else.

And the 10 years old bugs are to a large extent an exageration, because those modules are probably abandoned and you shouldn't use them anyway.

My experience with all of these has been that they've been frustrating to work with, and general support for them in the broader ecosystem is lacking and mutually incompatible.

Yes, that's the point, the ecosystem is now lacking because of the number of abandoned modules (even for quite common stuff).

Mojo::IOLoop is quite lean and straightforward to work with, but it's quite minimal. If I'd pick something, I'd probably pick this one as the decision to use Mojolicious was very rewarding.

AnyEvent is harder because it uses closures everywhere but it works really nicely otherwise. It's not endorsed by some in the Perl community because the author insists that it doesn't need a license and chooses to develop it and track bugs on his own infrastructure. EV is developed by the same author and it requires a compiler, it can be plugged into AnyEvent. They're both very good quality.

IO::Async is a different event loop brought to you by the people that do not endorse AnyEvent but are involved with Perl 5 development. I haven't used it, but it has a large number of active bugs on RT, plus past criticism from the author of AnyEvent.

There's also POE which we use but it's possibly on life support and you probably wouldn't want to use it unless you want to live in callback hell, so I fully understand your frustration if you've actually tried it. We use POE in a critical part of our infrastructure and has worked fine, but that part is quite frustrating to maintain. Futher criticism of this event framework could be found here:

As a sidenote, I'm curreny working with Ruby's Async:IO which is a breath of fresh air compared to other event loops that I've worked with in the past.
