There's one extremely significant example where the *value* of
something impacts on the type of something else: functions. The types
of everything involved in str([1]) and len([1]) are the same but the
results are different. This shows up in PyPy's type annotation; most
of the time we just track types indeed, but when something is called
we need to have a pretty good idea of the potential values, too.
Relavent to the point at hand? No. Apologies for wasting your time
:)
Cheers,
