As the subject. The obvious way:
I want the `scope exit 2` to come after the `F`. Is there a
way to tell it that I want to use an enclosing scope or make it
ignore the scope on the `if`?

This code can make "scope exit 2" be output at the end.
```d
import core.stdc.stdio;
import std;
enum exitcb = `scope void delegate() exitcb;
scope(exit) if(exitcb) exitcb();`;
int test(int val)
{
mixin (exitcb);
writeln("A");
if (val % 2 == 0)
{
writeln("b");
scope (exit)
exitcb = { writeln("scope exit ", val); };
writeln("c");
}
writeln("F");
return 2 * val;
}
void main()
{
writeln("== start =========================");
int v1 = test(1);
writeln("== 2 ==============================");
int v2 = test(2);
writeln("== end ===========================");
}
```
