Thoughts from the master (FYI). I don't really have an opinion either way on
Jelly, other than thinking it is very cool and useful. There's no reason it
couldn't be _another_ view option if people wanted it that way.

Then don't use a python EL - duh.

Its very common for folks to want to use Jexl / OGNL as well as XPath.
There's 3 ELs already. The use of JXPath on beans is quite common - that
makes 4. Noones forcing any of these on you.

Jelly is very simple. It takes XML and turns it into a Script of Tags and
Expressions which has variable scopes (JellyContext). Thats about it. Kinda
like Velocity but using pluggable expression langauges and Tags (as the
macro metaphor)

Like Maven, Latka, Anteater, JellyUnit, Werkflow, JellySwing. I guess
they're not real world enough?

Current dependency of the Jelly core is 5 jakarta commons jars (all of which
are small and could be replaced with a single jakarta commons core jar)
+ dom4j + JAXP.
