I agree with don. IMHO, this is incredibly silly given Andrei's use case, since D can have instead: void foo(const Widget); and have an optimization inside the compiler for value types to pass by ref. by specifying "const ref" you explicitly require that only a ref to an l-value be provided, whereas without the "ref" an r-value is also allowed a-la c++. much KISSer.
