You're right: it's not a closure any more.  That seems to be an
uncomfortable inconsistency with lambda: whether or not it generates a
lambda or a closure depends on when and how it's evaluated.

Somehow, my code runs OK.  It seems the stack frame in which the lambda
is generated is also the one from which the funcall is invoked.  Or
something like that.

I hope you'll forgive me pointing out that the doc string and section in
the elisp manual haven't been updated to describe these complications.
