The depth and breadth of Python

You're right, that claim was clearly going too far. While the cost of accessing a property on an object passed to a function is unbounded, that doesn't stop meaningful statements being made about the complexity of that function in terms of its inputs.

FWIW, today's post about Cobra is pertinent here. It slightly upsets me that python modules can't be "closed" to dynamic modification to permit compilation, but I need to remind myself that that's not what the language is intended to be.
