"The first expression may also be a tuple of length 2 or 3.  In this case, "
"the optional parts must be omitted.  The form ``exec(expr, globals)`` is "
"equivalent to ``exec expr in globals``, while the form ``exec(expr, globals, "
"locals)`` is equivalent to ``exec expr in globals, locals``.  The tuple form "
"of ``exec`` provides compatibility with Python 3, where ``exec`` is a "
"function rather than a statement."
