FIXME: clean up this description.

We model control flow like this:
|
||||
|
||||
(cond) <--+
|
||||
(expr) <-+
|
||||
| |
|
||||
v |
|
||||
+-- (expr) |
|
||||
| | |
|
||||
| v |
|
||||
| (body) ---+
|
||||
|
|
||||
|
|
||||
v
|
||||
(succ)
|
||||
(body) --+
|
||||
|
||||
Note that a `continue` expression targeting the `loop` will have a successor of `expr`.
|
||||
Meanwhile, a `break` expression will have a successor of `succ`.
