Indeed, it's not the best example: a better one is a procedure
that returns an undefined value, rather than a primitive syntax
form.  The idea is that it should be possible to call an unknown
procedure without having to defend oneself against receiving
multiple values quite as carefully as would be required if all
mutators truly returned no values (as opposed to a no-value value).
There are still things like exact-integer-sqrt, of course, that
can trip you up.

If I were you, I'd just say that raise-continuable is not supported.
It's part of the close JVM integration that Kawa is intended to achieve.
