Yes, I think so too.

It was a question for this only 98% serious (and 2% funny) kind of quiz,
so I tried to obfuscate a bit what is going on.  OTOH using let* I could
add the implicit question about how shadowing works in `let*' - that
question had been asked just some days ago, so I guess I couldn't
withstand.

Your form is better to demonstrate the binding aspect.

Michael.
