Fortunately, the Python interpreter is easily called recursively, and there is a
standard interface to call a Python function. (I won't dwell on how to call the

look at the implementation of the :option:`-c` command line option in
:file:`Modules/main.c` from the Python source code.)

An alternative strategy is called :dfn:`automatic garbage collection`.
