This is news to me too. It looks like this is the case in docgrok.py
however - a grokker is defined that looks for things called handle_.
While this is an example I used in Martian, I don't think it would be
good to actually pick up functions. The problem with this approach is
that one JW ran into - you can't define functions that start with that
A better pattern would be to define a docgrok specific base class and
look for subclasses of those. This eliminates the risk of namespace
*If* we want to actually grok functions, let's only grok those that are
actually decorated, like the example of @grok.subscriber.
