Right.

Something like, if the class contains the next attribute with a defined 
setter, it is used, otherwise nothing happens.

It would be a simple case then to define library functions, the obvious 
one being to assign all the signals:

from myhdl import interface_setter, interface_getter

class MyInterface(object):

     def __init__(self):
         self.a = Signal(intbv(0)[5:])
         self.b = Signal(intbv(0)[5:])

     next = property(interface_getter, interface_setter)

This could obviously be done in a parent class.
