Eval this:

  (lambda () x)

Same thing, no let-closure. Aren't lambdas like
that everywhere?

let-closures are not hard to understand, put a bunch of
`defun' in a `let' and use the variables like they were
globals, only they are not ...

Grep your source for global variables. Those are the ones you
can get rid of using let-closures, and without changing the
code using them. (Possible exception, for practical reasons:
Emacs options.)
