I sort of see where you are coming from.  Would you also say that
Self's inline object defination syntax:

  (|slot1 = foo. slot2 = bar| code)

is a form of lightweight meta-programming?

BTW, I refer to the representation as an array representation because
in JavaScript arrays can have string indices.
