84 | |

87 | |
88 The first argument is a :class:`Context` that represents the | |
89 JS context which is calling the function. | |
90 | |
91 The second argument is an :class:`Object` that represents the | |

113 function returns nothing. | |
114 | |
115 If `object` was created with :meth:`new_function()`, then this | |
116 method effectively "unbinds" the Python callable wrapped by | |
117 `object`. If `object` is later called, an exception will be | |

123 object/scope. | |
124 | |
125 It's assumed that `code` is coming from the file named by `filename`; | |
126 the first line of `code` is assumed to be line number `lineno` of | |

135 of ``this`` when the function executes, `func` is the | |

137 to pass to the function. | |
