Okay, different post for my actual questions.  :)

On the PyPI page for strait (http://pypi.python.org/pypi/strait/0.5.1) it has the example of choosing which methods to keep in the composed class:

class TOSWidget(BaseWidget):
    __metaclass__ = include(Pack, Place, Grid)
    info = Pack.info.im_func
    config = Pack.config.im_func
    configure = Pack.configure.im_func
    slaves = Pack.slaves.im_func
    forget = Pack.forget.im_func
    propagate = Pack.propagate.im_func

My question is:

Why use

    info = Pack.info.im_func

instead of

    info = Pack.info

?

Any and all enlightenment appreciated!
