While I don't pretend to have any idea how much the "typical" Python
programmer uses nested scopes, I am tempted to agree with you that
their use is quite common. However, I did not want to start a debate
(with Terry or anyone else) about the _absolute_ frequency of nested
functions, and so decided to phrase my statement in terms of an
agremment on the _relative_ infrequency of nested functions as
compared to unnested ones.
