You're right, but the problem Mark cites is a big one and it stops any
general call/cc or coroutine extension from going into JS.
I'd just add that call/cc in Scheme is a power tool, and (I'm told)

and Dave Herman did give them careful consideration. Dave alludes to
that work here:

which is deferred and pretty much defunct due to generators.
