Really, that's an excellent summary, much more readable than the perl5 delta.

I hadn't realized that unicode handling had been sped up a bit: that sounds like one of the more practical advantages. I know at least one place that's still running on 5.6 perl because they saw a 30% slowdown in their attempt at upgrading to perl 5.8 (they didn't know about "use bytes", but cut them some slack, that's an easy thing to miss).

My personal favorite new feature would be the improvements to the regular expressions: it's now possible to do recursive regexps in a much neater way than the experimental features in 5.8 (no, I don't actually have a use for this, but I still think it's really neat...).

    [Corion]: ambrus: Yes but I also need to implement the file / IO watcher, because Prima has that (in Prima::File), and I need to supply the appropriate thing to make push_write etc. work with Prima
    [ambrus]: Corion: yes, you need to implement the io watcher, which should be simple because Prima::File is basically that, and the timer watcher form Prima::Timer
    [Corion]: ... or so I think. As I said, I'm somewhat vague on how to make AnyEvent cooperate with a callback-driven IO event loop that gives me callbacks when data is available or can be written
    [ambrus]: what push_write thing? I don't think you need that. that's implemented generically by AnyEvent::Handle
    [Corion]: ambrus: Yeah, that's what I think as well. But you give me an idea, maybe I should start with implementing the timer, as that should be far simpler and with fewer edge-cases/nasty interaction than the file watcher
    [ambrus]: You only provide the watcher part that tells when the handle is readable or writable, not the actual writing and reading.
    [Corion]: ambrus: Hmmm. It makes sense that AnyEvent would implement the push_write itself, but I think I don't have a good idea of where the boundary between AnyEvent and the underlying event system lies... Implementing the timer should give me a better idea
    [ambrus]: Corion: push_write is in the higher level abstraction of AnyEvent::Handle, not in the watcher
    [Corion]: ambrus: Hmm - rereading Prima::File, that merrily coincides with what Prima does - it tells you "you can read", and you're supposed to read from the fh yourself. I thought it called you with the data already read, which would've been harder to integrate
    [ambrus]: you just need an io watcher, created by &AnyEvent::Impl:: Whatever::io(...)
