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.
