Eh?  You still have adapt(); you still have adapters.  The only difference 
is that I've specified a way to not need "interfaces" - instead interfaces 
can be defined in terms of individual operations, and those operations can 
be initially defined by an abstract base, concrete class, or an "interface" 
object.  Oh, and you don't have to write adapter *classes* - you write 
adapting *methods* for individual operations.  This can be done by the 
original author of a class or by a third party -- just like with PEP 246.
