Inspecting interactively created classes

import inspect, sys

def new_getfile(object, _old_getfile=inspect.getfile):
    if not inspect.isclass(object):
        return _old_getfile(object)
    
    # Lookup by parent module (as in current inspect)
    if hasattr(object, '__module__'):
        object_ = sys.modules.get(object.__module__)
        if hasattr(object_, '__file__'):
            return object_.__file__
    
    # If parent module is __main__, lookup by methods (NEW)
    for name, member in inspect.getmembers(object):
        if inspect.isfunction(member) and object.__qualname__ + '.' + member.__name__ == member.__qualname__:
            return inspect.getfile(member)
    else:
        raise TypeError('Source for {!r} not found'.format(object))

In standard Python (3.5.0) shell the result of a quick test is "". I assume the shell didn't linecache that.
