Sorry about that. I did not mean to be so gruff in my reply.

The problem I see with this text is that the continuation captured in
'generator' may not be the one your text suggests. Consider
(let ((x (call-with-current-continuation
(lambda (c) ...))))
One other point (a small nit I admit), is I prefer the phrase "the
'generator' is called to yield some values" to "the 'generator' is
first thawed (evaluated to yield some values)" but this is what
editors are for.
