For some reason I'm not attracted to that idea like I was
top-level lexical let-closures, i.e.

(let ((...))
  (defun (...) ...) )

but I should take a look at that document and not just make up
my mind, alltho that works most of the time by now since
I trust my intuition which is a trained skill like any other.

Okay, so when are oclosures used?
