Is that really the only reason they aren't being allowed? 
Whenever I use const& in C++ I generally don't want to copy or 
move anything. How about adding a new qualifier?

     void func(ruleThemAll(Foo) foo);

     const Foo f;
     func(f);     // ok
     func(Foo()); // ok

// ---

     void func(ref ruleThemAll(Foo) foo);
     void func(ref const Foo);        // error: ruleThemAll can 
have no overloads that match
                                      // function(Foo) or 
function(ref Foo)
