I think it could help in cases like namedtuple, where names can be part of a data description (e.g. coming from a database) and then used for attribute access. I do not find it extremely pretty, but I like it much better still than the "allowing keywords as names" proposal. It also has the nice side-effect that it doesn't make it easier to add new keywords, since the common spelling (e.g. `np.where`) would still become a syntax error and therefore break compatibility with existing code.
