[Zope] Re: ZTUtils.Iterator value in ZPT

[David Pratt]

Hi Chris. I believe the purpose of ZTUtils are utility functions for 
page templating. That said, the Iterator class could be more useful by 
exposing its values based on its state -  the point I had made.  
Versatility is the beautiful thing about python  - it rarely matters to 
me what intention there is or may have been for a class so long as it 
supplies the methods I am after.  In the end, there's really nothing 
here that can't be solved with a simple tool and a bit of flexibility 
on my part. Many thanks.

Regards,
David
