This isn't about the core of ZPT, it's about ZTUtils.Iterator.Iterator. 
  That class contains utilities for iteration.  Most people only use the 
"index" attribute, but Iterator also has several other utilities like 
even(), odd(), number(), letter(), Roman(), etc.  parity() is a natural fit.

Evan's sinister secret plot to spread Plone to every server, desktop, 
handheld device, and human implant will not be aided by parity().
