Please discard option 1, I'm afraid it creates too much
confusion and was not well thought through. The objective was
to expand 'auto ref T' to either 'in ref T' for lvalues or 'in
T' for rvalues (I.e., only for const parameters!), but then its
caption would be horribly misleading (and something like 'in
auto ref' would be way too ambiguous).
Maybe a very simple change/addition; Like perhaps @ref?
(Attribute ref, Alternate ref, auto ref.. All sorta fit for it's
meaning).
So...
void func1(ref int x); //D lvalue-only ref
void func2(@ref int x); //works like c++'s ref
Seems fairly easy to tell apart, and still leaves const-ness as
an option.
