I looked at (info "(elisp) Lexical Binding") and 
(info "(elisp) Converting to Lexical Binding") and it was educational,
though a few examples would have been nice to explain how it all works,
especially what the resulting `closure' cons cell looks like.  Would you
like me to write something up?

(info "(elisp) Extent") incorrectly says that Emacs Lisp does not have
closures so it probably should be fixed.  I don't know the details well
enough to offer a patch.
