Yes, sorry.

In Zope 2's ZPT, each namespace ('python', 'path', 'exists', etc) is
also available as a function taking a string.  Thus the TALES
expressions "exists:x/y" and "python:exists('x/y')" are equivalent,
although the latter is less efficient.

This isn't fundamental or anything, I just thought I'd point it out.
