[Types-sig] Ready for the next step

[Raymond Hettinger]

We've got two wonderful suggestions on the table:

Ka-Ping Yee's  class Spam(Interface)
Tim Hochberg's def spam(egg:Integer, beans:File)

The two suggestions do not conflict, meet many of the
project goals, and are straightforward to implement.

Let's get wild, bundle the two together in PEP and
see if we can all get behind it.
