Summary: overintelligent slice() behavior on integers

Initial Comment:

slices such as a[:7] give a key of slice(0,7,None)
whereas a[:7.1] gives a key of slice(None,7.1,None)

Slices should not assume that the object indices
begin at zero, since that is actually a characteristic of 
the object.  The current behavior cripples an object that 
wants, say, to start its indices with negative numbers.

a[:7] should pass a key of slice(None,7,None).

Thanks!

How does having 'slice' not round its arguments have anything 
to do with assuming indices start at zero?
