def afunc(...)

Because that's the preferred style for the Python standard library.  As 
long as I'm introducing new functions anyway, I might as well conform to 
stdlib.  While at present it seems unlikely PyProtocols will ever become 
part of the stdlib, I might as well remove any obstacles I can.

as a factory_method keyword to 'instances_provide()'.
