Well, first of all, you can use PageTemplates macros like in Zope (more 
like in Zope 2 than in Zope 3, actually).

One way to do it would be:

1. make layout.py with the following lines:

      import grok
      from zope.interface import Interface

      grok.context(Interface) # register stuff for all objects

2. make a layout_templates directory

3. inside that directory create layout.pt and let it define a macro.

4. use the macro using the following TALES expression:

I suppose something that makes working with ContentProviders easier and 
easily grokkable would ansewr this need. I'm not sure this has to be 
part of grok. This could also easily be an extension (megrok.viewlets or

Well, you could experiment with a viewlet mechanism for grok as 
suggested above. Any input would be highly appreciated!
