I disagree. Closures are rare in Python because Python is primarily an
OOP language.

"""The venerable master Qc Na was walking with his student, Anton.
Hoping to prompt the master into a discussion, Anton said "Master, I
have heard that objects are a very good thing - is this true?" Qc Na
looked pityingly at his student and replied, "Foolish pupil - objects
are merely a poor man's closures."
Chastised, Anton took his leave from his master and returned to his
cell, intent on studying closures. He carefully read the entire
"Lambda: The Ultimate..." series of papers and its cousins, and
implemented a small Scheme interpreter with a closure-based object
system. He learned much, and looked forward to informing his master of
his progress.
On his next walk with Qc Na, Anton attempted to impress his master by
saying "Master, I have diligently studied the matter, and now understand
that objects are truly a poor man's closures." Qc Na responded by
hitting Anton with his stick, saying "When will you learn? Closures are
a poor man's object." At that moment, Anton became enlightened. """
