You got the terminology wrong. Python had "types" from the very start.  
You're talking about some kind of generic functions, or an alternative  
dispatch method.

Read this GvR blog post [1] and his next one; also see PEP 3124 by Phillip  
J. Eby, who wrote a pretty good implementation of generic functions a long  
time ago.

Your proposal requires a syntax change and three new keywords; all the  
others achieve roughly equivalent results without requiring any change to  
the core language.
