Sort by dependencies... But is there any obvious way of dealing with
feedback loops, or do you explicitly have to specify where you want
the delay? Maybe there should just be a way of hinting delay
sensitive connections for when you actually have problems?

Makes sense - but I think it would be nice to be able to deal with
these kind of problems when you need to, so you can do filter
prototyping and stuff without going back to C. Prototype first, then
maybe hack an optimized .c fragment.
