For __setitem__ yes. There is some code in Plone and other products
that does:

actions = types_tool._cloneActions()
for action in actions:
  if action['id'] == 'view':
     action['action'] = 'folder_listing'
types_tool._actions = tuple(actions)

(or something to that effect).

Notice that im restricting the values that can be read and set to a
small set ( _props ), and that __setitem__ behaves differently for
'action', because it needs special treatment when being set.

| Yep, no problem there.

Hey, nice tip!
