Minified/Packed jQuery + Plugins...


This is a question/suggestion w/regards to shrinking jQuery and
related plugins.
As I understand it, packer replaces variable/functions with short
psudeonyms and indexes keywords to be evaluated at runtime, as well as
few other tricks.
Presumably, this means that there are size + performance gains to be
made by (a) including all the scripts you need within one js file that
is then packed -OR- by (b) some clever trickery where the same index
of keywords/functions/variables could be re-used.
Does anyone know if option B is possible or is being used? It seems
that would be a way of further shrinking plugins/UI components
(especially UI's like dimensions that are used a lot elsewhere).
Alternatively, it would be great if the UI page could provide packed,
single script, versions with any combination of UI elements, achieving
option A (not that I'm asking too much or anything :P)
It would be interesting to see what kind of gains could be made.. at
least a couple of kb per include?
