Comment(by allison):
Talked with NotFound about this on IRC. To summarize:
Any call to a coroutine will have to know if it is the initial call (where
arguments are passed) or a subsequent call (where arguments are not
passed). So, the best default behavior is to allow the coroutine to "die",
rather than to implicitly "ressurect" it and start from the beginning.
But, we do need a way to restart a dead coroutine (and possibly even to
restart one that is currently active). The two best suggestions were a
'restart' method on the coroutine object, and an optional named argument
'restart'=>1 passed in with the other arguments to the coroutine. The
method is simplest, and so could be implemented first. The optional named
argument is a possible future refinement.
