> keys are not variable names, so I'll ask (in general) why should obj be treated so special or differently?

There is at least some precedent of special treatment. In JavaScript's object literals, for example, you can do

  {a : 1, b : 2}

instead of

  {'a' : 1, 'b' : 2}

Then again, in other languages like Ruby, the keys must be explicit symbols:

  {:a => 1, :b => 2}

I'm not sure what the prevailing trend is on this (or whether knowing so would help to inform us about which is the better design choice).
