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,
