[Python-Dev] Re: A small proposed change to dictionaries' "get" method

Is this new method going to apply to dictionaries only,
or is it to be considered part of the standard mapping
interface?

If the latter, I wonder whether it would be better to
provide a builtin function instead. The more methods
are added to the mapping interface, the more complicated
it becomes to implement an object which fully complies
with the mapping interface. Operations which can be
carried out through the basic interface are perhaps
best kept "outside" the object, in a function or
wrapper object.
