Well, I am definitely interested in this. I had no idea this was being
planned. (I'll have to pop over to the OGNL site more often now) It
definitely would be good for us to keep in sync since we may be
duplicating efforts. My work thus far has been mostly a Proof of
Concept, so I haven't invested too much time at this point. It would
also probably be easier from a migration standpoint if we could get
something like this going.

I don't know how relevant it is to the conversation or how awful it's going
to be trying to do it but I did plan on taking a stab at creating a new
unified-el compatible grammar for OGNL when I do my big IoC-friendly
re-factor. (probably a 2.7.3 release kind of change)
Since jboss and others already sound like they do some el extensions of
their own to support parameter passing / other things it hopefully won't be
too bad. I'll try and post updates wherever I can to get more people
involved but knowing how you want to handle backwards compatibility ->
unified el + ognl stuff (if at all) and if OGNL needs to perform any extra
tricks to make it happen would be a good thing to have ready and discuss /
etc during that dev cycle.
I'm guessing I'll probably start on it sometime this month and finish
"whenever". .

I was working on a proof of concept for Unified EL:

I had a basic value stack up and running, however, I never took it any
farther than that. Richard Burton is planning on implemented an MVEL
stack in the near future, but he's waiting on some changes from Chris
Brock in MVEL itself.
I think in the long run, we really need a new tag library to fully take
advantage of the unfied EL. Even if we do that though, standard unified
EL is not as powerful as OGNL. We would need to extend the language or
be limited when compared to what is possible with OGNL today. Maybe for
some people that's not an issue, but I fear that would keep some people
from switching.
