Knowing this, we can sort a list of integers using an anonymous function.

List<int> numbers = [4,1,3,5,7];

numbers.sort((int a, int b) {
if(a == b) {
return 0;
} else if (a < b) {
return -1;
} else {
return 1;
}
});

Anonymous function may also be bound to identifiers like so:

Function intSorter = (int a, int b) {
if(a == b) {
return 0;
} else if (a < b) {
return -1;
} else {
return 1;
}
}

and used as an ordinary variable.

numbers.sort(intSorter);
