11 *
12 * Function objects are created by the execution of the 'def' statement.
13 * They reference a code object in their __code__ attribute, which is a
14 * purely syntactic object, i.e. nothing more than a compiled version of some
15 * source code lines. There is one code object per source code "fragment",
16 * but each code object can be referenced by zero or many function objects
17 * depending only on how many times the 'def' statement in the source was
18 * executed so far.
