-This statement supports dynamic execution of Python code.  The first
-expression should evaluate to either a string, an open file object, or
-a code object.  If it is a string, the string is parsed as a suite of
-Python statements which is then executed (unless a syntax error
-occurs).  If it is an open file, the file is parsed until \EOF{} and
-executed.  If it is a code object, it is simply executed.  In all
-cases, the code that's executed is expected to be valid as file
-input (see section~\ref{file-input}, ``File input'').  Be aware that
