Ah, thanks.  I've fixed this in CVS.

I've made them _cook_check() on each access of .macros, which is lazier and 
handles changes in debug mode.

The whole "Ambiguous name" business is intended to highlight places where a 
Product author is using the same object under more than one name, without 
explicitly declaring which name's security declarations are authoritative. 
With the changes I've made, the proper way to handle this is with a 
constructor keyword argument:

   security.declarePublic('view')
   index_html = PageTemplateFile('www/fooView', globals(), __name__='view')
   view = index_html

Thanks,
