Simple Traits Questions

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!
