[Grok-dev] Re: we need a MethodGrokker

[Philipp von Weitershausen]

I have introduced a MethodGrokker base class on a grok branch called 
'philikon-methodgrokker' (the MethodGrokker base class will obviously 
move into Martian before the merging happens).

All tests pass except those that check whether permissions used in the 
following way exist:

   class MyXMLRPC(grok.XMLRPC):
       grok.require('doesnt.exist')

       # otherwise empty class

With the new MethodGrokker, this won't generate an exception because the 
referenced permission is never actually applied to any method (because 
the class is empty).

The question is: Do we want to keep raising an error in this case, or 
shall we go the "easy" (and actually cleaner) way of not doing anything? 
Note that an empty XMLRPC class doesn't do anything anyway (which is 
probably more worth of an error than anything else).
