Simple Traits Questions

[Ethan Furman]

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!
