The align.el package (see C-h f align RET) is meant to do those kinds of
things, tho it doesn't seem to have an alignment rule for the above case.
You can also try C-h f align-regexp.

pretty-column.el has function pretty-rectangle, which will work for the
example you've given--in a fashion.  I tried it out and got the
following:

>           (foo 2)   
>           (zz  3))  

If I choose the rectangle slightly differently, I get this:

align values in a lisp let form

[Kevin Ryde]

Is there a way to align values in a let when editing, ie. to go from

    (let ((x 1)
          (foo 2)
          (zz 3))

to

    (let ((x   1)
          (foo 2)
          (zz  3))

I made myself a bit of code to do it, but I'd be surprised if nobody
else has done something like this before.  align.el doesn't seem to
suit.
