I love the idea.  However, this could complicate working with C APIs, 
particularly regarding structs which are often passed by reference as a matter 
of course.  For example:

struct some_c_struct {}

void fn(ref some_c_struct s) {
     some_c_func(&s);
}

I guess the only way to know if this will turn out to be a real issue is to 
give it a try though.

This applies to static arrays as well:

extern (C) void foo (ref int[3] a);

Since in D static arrays have value semantics.
