i think this probably still needs further clarification. fibers (when used as a module as Marcel describes) takes a callback and within that callback you're in a fiber. this could be adapted to "when you're in a yield" instead of "when you're in a callback".
but, common-node (and maybe some other libraries) have abstracted away that callback when you're living in their abstraction by using fibers under the hood (i'm sure Oleg will pop in any minute to explain how). the way yield is described for generators does not lend itself to ever being abstracted to that degree. this isn't a judgement call about which one is better/worse, personally, i don't like fibers or generators :), but it's an important distinction for people who think that "all these callbacks" are a issue that needs to be solved by abstracting them all away (or in the case of common-node want to create a Narwhal compatible environment). one of these tools potentially does that (although it doesn't by default when used as a module) and the other never can.
