So, make a 2 closures and then alternate calling each where the first
increments an int, and the second prints it.
That is,
public void foo() {
int myInt = 0;
Runnable a = new Runnable() {
public void run() {
myInt++;
}
};
Runnable b = new Runnable() {
public void run() {
System.out.println(myInt);
}
};
a.run();
b.run();
}
If we had closures, you could do this, no? (Again, not being
rhetorical. This is just how I understand the situation.)
