That's still pretty much everything in Python. Off the top of my head,
the only manipulable things that aren't first-class are name bindings
themselves, and those can usually be simulated - most namespaces are
representable as dictionaries, and other bindings are
__[gs]et{item,attr}__ calls; the notable exception is function locals,
which you can't easily mutate from outside the function.
