I'm assuming that offset is lexically bound somewhere outside
the let expression so that I have to capture it with an in-place
FLET or LAMBDA.  If we had an external add-offset then I'd have
to do something like

   (add-offset offset some-list)

The problem with this is that you've essentially outlawed MAP.

   (map 'list (make-adder offset) some-list)

The problem with this is that MAKE-ADDER is no less a lambda in drag,
and it isn't even local.
