I've got a Zope 1.10.3 installation (to be Zope 2 Real Soon Now). I like to put certain functions (like tuple, map, list, and filter) into the standard namespace '_'. Up to now, I've patched DT_Utils to do this, but it's a maintenance PITA. I decided to try making a Product which would reach over and insert the functions, but it doesn't seem to work. It's just a directory under Products containing the following code in '__init__.py' (yes, there's an '__init__.pyc' too). # MoreBuiltins/__init__.py __doc__='''More Builtins Product Initialization''' __version__='$Revision: 0.1 $'[11:-2] classes=() meta_types=() methods={} misc_={} __ac_permissions__=() from DocumentTemplate.DT_Utils import TemplateDict d = TemplateDict.__dict__ # Test insertion d['whizzo']='chocolate' The Product appears in the Product management folder, but <!--#var "_.whizzo"--> gives an AttributeError. Help?
