D has ref variables? Not for a long time though.
D actually does not support ref local variables in most contexts (one
can have ref locals declared by foreach). There is an explicit check
ruling them out, but I'm pretty sure DMD supports them internally, they
are useful for lowering.
Of COURSE D supports local ref variables:
struct RefVar(T)
{
private T * var;
this(ref T v) { var = &v; }
auto get() { return *var; }
alias this get;
}
