Thanks for helping me solve this one. In the end I did the following:
1) hacked DocumentTemplate/DT_Util.py to include "filter" in the __builtins__
2) Installed PythonMethods and called pruneTree with parameter 'self' and content
return _.filter(

Python's ideas of 'built-in' is simply any method in the module

Nope. Lamba, filter, reduce, and map should IMHO not be part of DTML.
Actually, exprs probably shouldn't be in there in the first place.
People are trying to use DTML as a way to process non-UI elements. This
is a slippery slope, and leads to something like PHP or

Minor note:
"lambda" is not a builtin but part of the syntax (a keyword).

What I would like to say is that if your application needs lambda, filter or
map, your code is getting bejond report or presentation generation (for which
DTML is intended) and in the realm of data manipulation and business rules. In
this case your code would be much better placed in some
