And we can't go letting the 6502 boys have all the fun!
I've had lots of fun with my pure-Perl MIX assembler and simulator as well :-)

More seriously though, this is a nice example of closures.

    Of course, MIX is a whole machine, not just a CPU.

    Implementing a usable machine around my emulator, with I/O etc, is next on my to-do list!

[Corion]: ambrus: Yeah, I read that, but it's somewhat vague as in what I really have to implement, and where/how my "other" mainloop should/needs to call AnyEvent
[Corion]: (or maybe I just work better from existing code that I munge until it works and I understand it rather than a short abstract text like "implement everything that's needed" ;) )
[ambrus]: Corion: I think in this case you can get away with only a stub for idle, one that always dies when you create it, because AnyEvent::HTTP doesn't use it, not even indirectly through AnyEvent::Handle or AnyEvent::Socket or AnyEvent::DNS.
[Corion]: The "and I understand it" part is optional.
[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
