I agree this would be the most natural, but if it does slow down
evaluation (which I think it would), then it isn't worth the cost.
OTOH, it might be interesting to apply this logic to `defun's, since
they already handle `declare' forms anyway.

If this is chosen, I would find the following form more natural:

(lambda-with-doc-string (foo bar)
  ;; First body form is evaluated at compile time and must return a string.
  (concat "Toto is very " blabla ".")
  ;; Everything else is a regular lambda.
  (code using foo and bar (and blabla as well)))
