Properties: a.b.c = 3

[Walter Bright]

The issue is what if b is a property, returns a temporary object, and 
that temp's .c field is uselessly set to 3?

It's a classic problem with properties that are implemented as functions.
I don't see how C#'s special property syntax adds any value for dealing 
with this.

One thought I had was to simply disallow the '.' to appear after a 
function style property.
