Don't forget the 'as' clause.

A "template invocation", perhaps, for the statement, and a "templated
block" for the actual block. The expression part of the statement would be
the "template expression" which must result in a "template iterator".

help(synchronized) or help(retry) would doubtless display useful
information. Conversely, try Googling for Python's "for" or "if" keywords,
and see if you get anything useful -- I didn't.
