Bug report
_PyFunction_FromConstructor creates a PyFunctionObject, populating its fields by pulling them from a PyFrameConstructor object. But it ignores the fc_closure field, which means it always creates a function that has no closure. Creating functions with closures is a totally legitimate use case and this is just a bug.
