[Zope] Problems calling directory

[Tino Wildenhain]

Hi,

this is a common understanding problem. To get a feeling
whats bad, try to start the python interpreter
and type in the following:

class dummy:
	def __getitem__(self,key):
		return(getattr(self,key))
# two newlines here	

a=dummy()
b=dummy()
c=dummy()

b.c=c
a.b=b

you now can access c thru a and b like this:

a.b.c

or a['b']['c']

but you cannot use a['b.c'] to access c, since
the objects names are 'b' and 'c' and not 'b.c'
