If you're getting security errors, try this new version (untested):

class simple(Acquisition.Implicit)

	__ac__permissions__ = (
				('View',  ('get_value','get_list'),('Manager','Anonymous')),
			      )

	def __init__(self,value):
		self.value=value

	def get_value(self):
		return value

Globals.default__class_init__(simple)

Now, hopefully, theList is being returned from within a class method, in
which case:

   theList = [simple(1).__of__(self), simple(2)__of__(self),
simple(3)__of__(self), simple(4)__of__(self)]
   return theList

then:
<dtml-in get_theList>
     <dtml-var get_value>
</dtml-in>

should work...

hmmmm,
