+A reference is a handle to an object, like a pointer, but is automatically dereferenced by the specified number of levels.
 Referencing (address-of @&@) a reference variable cancels one of the implicit dereferences, until there are no more implicit references, after which normal expression behaviour applies.

 The resulting execution system now follows a cooperative threading-model, called \newterm{non-preemptive scheduling}.

+Because the scheduler is special, it can either be a stackless or stackfull coroutine. \commenttd{I dislike this sentence, it seems imply 1-step vs 2-step but also seems to say that some kind of coroutine is required, which is not the case.}
 For stackless, the scheduler performs scheduling on the stack of the current coroutine and switches directly to the next coroutine, so there is one context switch.
 For stackfull, the current coroutine switches to the scheduler, which performs scheduling, and it then switches to the next coroutine, so there are two context switches.
-A stackfull scheduler is often used for simplicity and security, even through there is a slightly higher runtime-cost.
