During the Melbourne Zope3 Sprint, someone ran up against a situation where they'd have liked to have TALES perform a tuple unpacking like Python can. I've just run into a similar situation :)
Say a method listFilesByUser returns a list of (user, [files]) it'd be nice to be able to::
tal:repeat="user,files here/listFilesByUser"
or similar. Currently we would have to use a python: expression to manually unpack the tuple. Kinda yucky.
I agree that it is 'yucky', but I have to disagree with your proposed solution. I would rather suggest making TALES aware of integer indexes for sequences. Example::
<tal:block repeat="user_files here/listFilesByUser">
User: <tal:dummy replace="user_files/0" />
File: <tal:dummy replace="user_files/1" />
</tal:block>Regards,
Phil
