Well, maybe 'very different' was an overstatement =).

One way to look at it is that we should use single-use functions as far as possible to keep code straightforward.

And as jpr said, LET* can potentially promote bad style, giving one the inclination to mix functional and imperative styles in a potentially troublesome fashion.

I think it was in 'On Lisp' that PG said that use of LET* should be minimised for the reasons above.

But if not, you're right. Use LET* just as you mentioned, but don't use LET* for all cases.
