Fortunately, Michael has not suggested that.

Michael has suggested optional syntax to explicitly declare attributes. 
He has not suggested to add attributes to the existing implicit lookup 

If "spam" is declared with "self spam", then it must be an attribute. 
Not a local, nonlocal, global or builtin.

If "eggs" is *not* likewise declared, then it *cannot* be an attribute, 
and the same implicit lookup rules that Python already uses will 
continue to apply.
