This seems like a defect of the language. Perhaps a new language 
feature is needed. Something like this:

void foo(inout T)(T t)

Pass a variable of type S, const(S), or mutable(S), and the 
function signature becomes:

void foo(S);

And then fails if your argument cannot be converted to mutable S.
