Not normal but it can be arranged. :p

import std.stdio;
import core.thread;

struct S
{
     void foo()
     {}

     void foo() const
     {
         Thread.sleep(dur!("seconds")(3));
     }
}

void takes_ref(ref S s)
{
     s.foo();
}

void takes_const_ref(const ref S s)
{
     s.foo();
}

void main()
{
     auto s = S();
     takes_ref(s);
     takes_const_ref(s);
}
