   It's already too late. But even if it wasn't, you seem to be saying that code   
   like:   
      
       void demo() {   
           int self = 1; // OK?   
           auto lambda = [&] { ++self; }; // Proposed error?   
       }   
      
   should not compile. I don't agree. Variable names shouldn't turn into keywords   
   just   
   because they are in a lambda expression.
