That seems like a contrived example. If you wanted the
function to have Docstring B, why did you give the given
block a docstring of its own in the first place?

In this particular case (i.e. a function that does nothing
but define and return another function) I'd like to be able
to write

   def decorator(f)(*args, **kwargs):
     do something...

but that's a subject for another hotly-debated PEP!
