What about
<ww:property value="firstHalf${secondHalf}"/>
? The advantage of the velocity-style escaped syntax is that it allows for
more flexibility, so that the whole thing doesn't have to get evaluated.
Also, what about tags where what could be displayed might be evaluated in
some cases, but might not in others? How can you build that logic into the
framework so it knows whether to be evaluated or not? I think the question
is not whether we should always evaluate or not, because that question has
been answered already by use of the "triple-quoting"; it has been decided
that it is more flexible to allow for values to be passed into tag
attributes that _can_ be evaluated against the stack but don't always have
to be. I agree with that approach. The question I'm raising is regarding the
way the syntax of those values is structured. I just don't like the
triple-quote approach.

I don't see why you are using java if you prefer that way of writing
personally.
Let's compare the alternaitves:
<ww:property value="name"/>
<ww:property value="${name}"/>
Am I wrong in assuming that simple usage of the variables is the most common
thing in the WW EL? Because if it is then implementing a more verbose syntax
for it is counterproductive. The rule of thumb is to make the most common
actions simple and intuitive and there is nothing intuitive about the ${}
syntax.
