Well, this is not accurate, as you can have 'infinitely-nested
scoping' in python, in form of nested functions. For example, you can
use map(lambda x: <expressions with x, including other
map/filter/reduce/lambda's>, list_of_x), and you will have your
isolated scopes. Although due to lambdas supporting only expressions,
following this style leads to awkward and complicated code (and/or
instead if, map instead for, and so on).
