Another poster asked about preferred syntax for infinite loops.

A follow-up question: Why do you use infinite loops in your code? I typically see a construct like this:

for (;;) {
  int scoped_variable = getSomeValue();
  if (scoped_variable == some_value) {
    break;
  }
}

Which lets you get around not being able to see the value of scoped_variable in the for or while clause. What are some other uses for "infinite" loops?
