suppose it's possible to support both. One interesting difference is
that my syntax says both get an attribute and call it,

How would you pass arguments in your version? I'd say that passing

If you need to pass arguments, use a Python expression

I guess I don't understand the goal. Are we trying to make it
so that zpt authors don't have to know any python?

For me, that would be ideal...

I really think that's a mistake.
Guys, that line of thinking is a distraction. ZPT authors ought to

in the separation of presentation from logic.
My view is that embedding logic in presentation isn't quite the right
thing to avoid. Consider how much logic goes into

Are you running the DynPersist extension from ZPatterns? That would
need to be recompiled.
Also note that python setup.py build doesn't reliably rebuild the
