Apple's Pascal had function pointers, and I'm pretty sure you could still do callbacks to nested procedures with a little trickery.

Ahh, I was right (PDF file here): http://mirror.informatimago.com/next/developer.apple.com/tec...

These are not closures, they're still strictly nested and on the native stack, so the usual crashes happen if you execute a callback to something that has gone out of scope.

Remind me to tell you about "Fork Queues", a solution we had on the Newton for dealing with multiple entities that all wanted to have the main event loop (of which you could really only ever have one, but we cheated).

Oooh, this sounds fantastic!
