While you can come up with such examples, they tend to always
be contrived.  In my experience, the benefit of `let` is only really
seen in macros, where you can do:

    `(let ((x ,arg1)
           (y ,arg2)
           (f (lambda (,z) ,@body)))

without fear of capturing an `x` that might occur inside `arg2` or `body`.
In hand-written code, having only `let*` and no `let` would make almost
no difference.
