Cf0x10 programs may be easily invoked from Python:

.. doctest::

   >>> from cf0x10.interpreter import Program
   >>>
   >>> p = Program('"Hello, world"')
   >>> p.execute(sys.stdin, sys.stdout, [])
   Hello, world

In your Python program, just decorate functions with ``@comefrom`` to make them eligible jump targets from Cf0x10 programs:

.. doctest::

   >>> from cf0x10.bindings import comefrom
   >>>
   >>> @comefrom('if who')
   ... def cf_greeting(io, scope):
   ...     io.stdout.write("Hello, %s" % scope['who'])
   >>> 
   >>> p = Program('who = "world"', additional_bindings=[cf_greeting])
   >>> p.execute(sys.stdin, sys.stdout, [])
   Hello, world
