OK, so this is the correct interpretation of
the question from the OP? I'm not sure it is,
but if it is, it is easier to answer.

`eval-region' is a bit of a trickster in my
book, I like `eval-last-sexp' better
(`C-x C-e'; place point after the
closing parenthesis).

Do it repeatedly if needed:

    (message "1")
    (message "2")
    (message "3")

If you do it repeatedly, you can either do it
faster with something like this - and bind it
to a even faster and shorter keystroke than
`C-x C-e', e.g. I have it M-a:

    (defun do-repeat-complex-command ()
      (interactive)
      (eval (car command-history) ))

This can be a trickster as well tho, as anyone
who tries it will realize quite soon :) But it
is useful as well, and not only in trivial
examples like the one above.

But the _best_ way of doing it if you notice
you do it a lot, is probably change the code
itself:

(progn
 (message "1")
 (message "2")
 (message "3") )
;;              ^ C-x C-e just once, with point here

HIH and please do clarify if we didn't answer
your actual question :)
