[Zope] Re: SortEx module feature request thinking

[Oleg Broytmann]

Hello!

   I hope you know the Sort and SortEx are now in Zope 2.4? Just under
different names :)

   Well, about your question: instead of predefined 'nocase' you can pass
your own function (see examples in SortEx tar.gz). And in this function you
can do whatever you want - you can determine types of your parameters,
compare them in any way you prefer, etc. SorEx is a framework you can use
to simplify your sorting needs!
