[Zope] Problem returning values from a catalog...

Hi, I ve got a very strange problem: I want to return a catalog value named 'from'. The problem is that i cant change the name of the value because its part of the tracker-source code(Maybe I could, but thats the worst solution). When I access the catalog in the way, for brain in catalog: print brain.from i get a error because the name from is a python keyword !! If you know a solution please let me know !! Otherwise i have to edit the tracker-source(urgh!) Thanx, Sebastian
