[Python-ideas] Re: Renaming json.load()

What happens when aliases collide with proper attributes? Could you have an attribute 'foo', combined with an attribute 'bar' with alias 'foo'? If so, how would that work?

Using a ChainMap makes this choice for us. The first level dictionary-- which would contain the attribute with the name collision-- wins.

What happens when a subclass of Foo adds an attribute that masks an alias defined for an attribute of Foo?

Again, the child attribute wins because ChainMap.
