Think about the desired feature mentioned earlier in this thread of
being able to insert a "return;" statement, causing what looks like a
function call to return from the caller.

I'm not entirely sure what you're saying. Could you please post a link
to the post mentioning this or show an example.

I believe it is basically this:

int bar() {
    foo(return 3);
    return 5;
}


If that program is allowed to compile, and to return 3.

That never was in the DIP.

It was this by Timon Gehr essentially posting why lazy parameters weren't good 
enough:

Ah, found the code:

void ifthen(bool cond, lazy void dg)
{
     if (cond)
         dg();
}

int foo(int x){
    ifthen(!x, return 2); // uh oh
    return 3;
}
