If you can get the data into a perl array, just use List::Util and the min and max functions.

[ambrus]: Corion: really? Does that mean the Prima watcher objects behave as handles that stop the watcher when they're destroyed, just like AnyEvent expects?
[ambrus]: "all the bugs" -- hehe, good luck
[ambrus]: Corion: what I don't understand is, if you make a one-shot AnyEvent timer with short timeout, does this code guarantee that the Prima timer can't queue two timeout events before invoking any of them?
[ambrus]: Because that could break AnyEvent code, which is why I added a guard.
[ambrus]: (It might be easier to use the callback scalar as a guard, as in $c and &$c(); $c = ();)
[Corion]: ambrus: Hurr - yes, that might happen, as Prima will queue lots of stuff (Well, Windows will)
[Corion]: But I'm really amazed that it just took this little code (plus the idle handler I have in mind and something else dk suggested)
