Handy it may be, but why is this usage important enough to deserve new 
syntax? The barrier to entry for new syntax is very high. For example, 
Enums are a common, and standard, feature in many programming languages. 
Enums will be introduced to Python in 3.4, but even they don't get 
special syntax.
