[Zope] How to determine if a object is wrapped by an acquisition wrapper?

[Johan Carlsson [EasyPublisher]]

What is the base way to determine if a object
is wrapped by an acquisition wrapper?

I currently use hasattr(seld, 'aq_base'), I would like
to use something like:

from Acquisition import isWrapped, Implicit

class Foo(Implicit,...):
   def bar(self, ...):
       if isWrapped(self):
         return "We don't serve wrapped object, sorry!"
