[...] little as possible. Therefore, in Javascript, expensive operations are performed asynchronously. I complained about asynchronous programming before, but it has the nice property of making explicit what operations are going to be [...]

Thanks, I'll have a look at that.

Trust me, the Perl code was not much better than the PHP code, because I started with that when I was learning Perl, go figure ;)

Hey Zef, the closest I've seen to making synchronous-style code asynchronous is via coroutines+greenlets+libevent:

http://www.gevent.org/

It gives you the flexibility to make requests in parallel if you desire, or you can stick to a serial approach (or a combination).

By the way I remember you from way back, I began learning how to write PHP by helping a bit with Yabb SE. I haven't looked at the code but I suspect the perl version was better-written ;)

Yeah, that's basically it, isn't it? I was thinking about that earlier. Have to look up the exact transformation.

Zef, remember “Transformation to continuation passing style”?

Take a look at Twisted's defer.inlineCallbacks for a working implementation of the sync -> async transformation.
