[Zope] sequence.sort: how can I sort strings?

[Danny Adair]

Hi!

How can I sort a sequence of STRINGS using sequence.sort?
I don't know what to use as a "key"...

(I tried self, str, value, '', _.None, ....... :-))

Or in other words: What's the attribute of a string that returns the string 
itself?

thanks,
Danny
