No. What I think is difficult is to implement a general recursive tree *and* an API for expressing properties of nodes that make them equivalent to the specialized hierarchy *and* a usable interface for specifying and managing those properties by non-programmer users (including admins). > Another case for generality is permissions.

I'm not opposed to generality in general. ;-) What's more important to me than whether you know all of the parameters that will be associated with a list :-) is that I'm pretty sure I don't want Postorius's views to know. That leads to ugly and unmaintainable code. I also don't want users to be seeing data they don't need to see, or shouldn't see, and they mustn't be able to change parameters they shouldn't change. These requirements can be fulfilled in a number of ways, including customization by extension modules. For example, there could be (extensible) lists of parameters attached to each role, a list for each permission. I think that's kind of fragile; better to attach an ACL to each permission. (I think that's basically what you have in mind, too.) _______________________________________________ Mailman-Developers mailing list Mailman-Developers@python.org http://mail.python.org/mailman/listinfo/mailman-developers Mailman FAQ: http://wiki.list.org/x/AgA3 Searchable Archives: http://www.mail-archive.com/mailman-developers%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-developers/archive%40jab.org Security Policy: http://wiki.list.org/x/QIA9
