callable() returns True for any instance. Since PersistentList is an
instance, you can't use callable() to determine whether it is
callable.

There is a workaround for this in the DocumentTemplate package. It
implements a safe_callable function that seems to do the right thing
with ext class instances:
def safe_callable(ob):
# Works with ExtensionClasses and Acquisition.
if hasattr(ob, '__class__'):
if hasattr(ob,
Hi!
In KeywordIndex the newKeywords get called
if they are callable:
def _get_object_keywords(self,obj):
newKeywords = getattr(obj, self.id, ())
if callable(newKeywords): # (*)
newKeywords = newKeywords()

Just a note that this can't be put in Zope 2.6 since functions and methods
don't have a __call__ in Python 2.1.
