I'd like to see a built-in shorthand to allow me to chain method calls even when a method call does not explicity return a reference to the instance of the object (self).

def newFunc02(): return NewList([8,9,7,1]).self('sort').self('reverse').self('pop',0)

My thought is that you're trying to write programs in some other language using Python.

If you really want all that on one line, you can do it already:

x = NewList([8,9,7,1]); x.sort(); x.reverse(); return x.pop(0)

which is just as compact and doesn't suffer from the weirdness of passing method names in as quoted strings.
