I am currently working in the required part of the compiler, but 
I need help and other opinions.
So far I've tried both: an implementation for auto ref and ref 
const.

  -> auto ref:
auto ref for non-template functions. In this case (as you had 
suggested it once) temporary variables are created for rvalues. 
Thus the behavior of auto ref would be different for template and 
non-template functions. But I do not see how that would be 
problematic.

  -> ref const:
const ref creates for rvalues a temporary variable that is then 
passed to the function. Advantage: It is like C++. Disadvantage: 
it could break code and you get always a const parameter.

As I said, I've tried both ways before. But I like to hear other 
opinions which of both would be more preferred.
And I would be glad about any kind of help (looking on my code 
etc.).
Maybe we could convince Walter and Andrei with a finished 
implementation.
I hope that no one like to have a new syntax for this kind of 
thing because then we will discuss another year...
