Sorry. I wasn't intending to be contentious regarding Plone. Evan just 
cited the prevalence in Plone being the drive being looking into this and I 
guess I've become quite conservative about features since I started with 
Python. I don't need the feature directly so I was trying to work out what 
was behind it and how something similar might be done which I could also 
use. I really like ZPT and the recent discussion re: if/else has shown how 
much thought has been done before anything is implemented.

While it might be a natrual fit that is in itself no justification. If 
parity() is added, then even() and odd() should be deprecated. However, I 
still prefer my own more declarative and explicit suggestion. I've no idea 
how this would work with iterators but my page design brain bit feels quite 
happy with this.
