If you need this for **kw arguments maybe you're not using them right;
why not name your arguments if you're going to reference them by name?

The JSON use case seems to be driven because this is the way
JavaScript does things -- they don't distinguish between dicts and
objects. I personally think that's a poor language feature: it blurs a
line that should be clear, between data (dict keys) and program
variables (attributes).
