If i've done this correctly, it should be impossible to alter the contents of the list or the counter, given only the immutable_facet or the readonly_facet, after restrict() has been called.
I'm probably missing something, but a straightforward reflection approach seems to work on my machine:
restrict() readonly_facet = facet(counter, ['value']) print readonly_facet.value() 0 readonly_facet.value.im_self.n = "oops!" print readonly_facet.value() oops! class mycounter: ... def value(self): return "muhaha!" ... readonly_facet.value.im_self.__class__ = mycounter print readonly_facet.value() muhaha! ... readonly_facet.value.im_func.func_globals["readonly_facet"] = myinstance ...
and so on does that restrict() function really do the right thing, or is my python install broken? </F>
