I'm from different school of thinking which is probably very incovenient 
in spec-thinking. But I feel strongly that there should be one more 
* It is an affordance with very little or no new semantic for an 
uncommon pattern which by its formalizing and makes "godel-accessible" 
(in the sense "comprehensible by one's mind") space covered by the 
language much greater.
(I'm talking about mixins / traits, mustache+richer data semantics, ...
