Basically, someone needs to implement it and then talk Walter
into accepting
it. That'll be easier for someone like Kenji, who's already a
major
contributor, but in theory, anyone can do it. It's just that
there's a high
risk that the pull request would languish for a while. And it
would probably
need to be implemented with a name other than auto ref in order
to avoid the
aforementioned problems, and having to agree on that could
cause further
delay.
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...
