I can't imagine how.  Do you have a scenario in mind?
No, As I said I'm not a compiler writer :(
 
I recognize that the added value is minor, but I'm sure that you have already desired to not name these variables.

Given the cost to adding language features, I just don't see a compelling case.

I just wanted to share a minor need that 'don't name what you don't need' ;-).
I understand that we can concentrate in more important features.
