Yes, that's why I proposed it. EIBTI.

Alas to reach consensus, we minimize. This happened with private names 
=> private name objects (API only, no "privat x" declarations), and now 
we are trying to add private declarations.back into ES6. (I hope we 
succeed.)

Could try adding explicit-this-parameterization too, but it's another 
straw on the camel's back.
