You are missing nothing here.  The notation just seemed very cute.

Always good to know! :-P :-)

(the env() function could also ensure that we also look up in the
enclosing environment, so it would not be necessary to use print=print
in the table.)

Note also that this kind of one-shot iterator could do something
interesting on the start of the second iteration before returning nil,
like finalizers.

Interesting points. thanks!
