textmate like auto pairings

[andrea]

I'd like to configure smartly my auto pairings more cleverly

I use this http://gist.github.com/259460
found I don't know where but I don't know how to configure things per
mode.
Looks its too much in the textmate.el code, I'd just like to set up a
list of assocs with a list of, something like:

--8<---------------cut here---------------start------------->8---
(defvar my-pairs '(
        (python-mode . '(
                         \( . \)
                         \[ . \]
--8<---------------cut here---------------end--------------->8---
...
Something like that...
