I was thinking that the old taglibs would just be kept around and they would
wrap the new underlying view code and inform them that they wish to use the
old ValueStack.

You're right, there have been very small (none?) changes to the EL. But on
the other hand, we've seen it's slow and by using an existing project we can
let us focus on the framework and let the Ognl guys focus on performance,
features, etc. Not a huge win, but I tend to like to offload to other
projects if they work the same way and are faster/better/more-featureful.

No. =) But it can do some stuff that would be useful that isn't a lambda
expression:
"someList.{?#this.startsWith('j')}"
That expression will give you a subList of objects that only start with "j".
Basically, you can use .{?#....} to select sublists.

I agree, [1] is a tag yucky, but I know that in my case (and I use ww
taglibs quite a bit) I usually only end up using ../ in very sticky
situations and you pretty much gotta understand what's going on to use it. I
doubt a simple web developer toys with ../ without knowing what it is, so
seeing [1] will be just as confusing. But for people that do know about ../,
it might take a few moments to get their head around [1].
Also, @foo would become #foo.
