Re: About ref used for performance reasons with struct

[Namespace]

Read my approach. I suggest something like A& a. It's short and 
known from C++.
Only in my approach, I suggest a link between the proposal of 
deadalnix (compiler optimizations) and generally rvalue 
references.
'const ref' will never work the way as we know it from C++. 
Walter and Andrei and many others are totally against it.
However, 'auto ref' is also not a real solution, because 'auto 
ref' generates 2^(n - 1) permuationen of the same function - code 
bloat.
'auto ref' accept of course lvalues and rvalues but you gain no 
performance.
