I've been asked about modular jQuery more than advanced compilation.  I'm glad you've done some work on this already.  You're probably one of the best people to do it. 

Fwiw, we wouldnt have to expose its modularity programaticly if we didn't want to.

I feel like I've missed some important discussion in which we're
making jQuery "modular" - a rather dramatic departure from anything
we've done so far and a rather stark change for the project as a
whole. Is there more information on this?
True, it is a big change, but maybe it is a change worth making?

The cons that I can think of are:

- It has the potential to increase overall filesize (we probably wouldn't want to do both this and cc).
- It would have a major effect on the overall structure of the library.
- It would be a weight on the simplicity of a single file (this may be a good enough reason not to do it).
- We would probably need to take the time to create a builder similar to UI or Modernizr.


- Unneeded modules can be removed by the user.
- No extra compilation and no advanced mode compatibility required.
- We can be compliant with the AMD specification and promote javascript modularity as best practice.
- We could even consider including require so that define/require/exports work automatically for AMD-compatible jQuery plugins (I know, that could be a stretch).
- We can do it without requiring changes to Closure

We could ask the community and see what answers we get.
