The three most widely-used event systems I know of in Perl are: - AnyEvent - IO::Async - Mojolicious These are all abstractions over various methods of polling: select(2), poll(2), or OS-specific ones like Linux’s epoll. For example, AnyEvent includes a select-based, pure-Perl loop but can alternatively work with libev via XS. All of these libraries have tradeoffs, so it’s hard for me to say, “I wish everyone would just use X.” That said, Perl would be much improved, in my opinion, if a good standard for I/O polling could emerge. -FG
