It's driving me insane. I can't take any more of this! >_<
Walter invented a solution that was very popular at dconf2013.
I don't
recall any problems emerging in post-NG-discussions.
Ideally, we would move forward on a design for 'scope', like
the
promising (imo) proposal that appeared recently. That would
solve this
problem, and also many other existing safety problems, and even
influence solutions relating to other critical GC/performance
problems.
IMO just legalese auto ref for normal functions and you are all
set.
The semantics end up to be pretty much the same as c++ const &
does (not duplicating the function, like current template-style
auto ref).
Yeah, the whole function duplication thing is pretty bad. Auto
ref should just create a wrapper that forwards, and the
implementation always operate on references.
With this approach in mind, auto ref for functions should be
trivial, in thé sense that the function is compiled normally as a
non template that takes refs, and the compiler only generates
code/templates to capture r values.
