In Dr Alexandrescu's "The D Programming Language", on page 12, it is noted that the D compiler will rewrite tail calls within a procedure as loops.  Does the compiler rewrite tail calls between procedures as jumps?

For example, in pseudo-D:

void foo(K)(K cont, stuff..) {
    // Do things with stuff.
    cont(things);
}

Is the call `cont(things)' optimized?
