I read http://stackoverflow.com/questions/839178/why-is-javas-iterator-not-an-iterable and http://stackoverflow.com/questions/27240/why-arent-enumerations-iterable, but I still don't understand why this:
void foo(Iterator<X> it) {
for (X x : it) {
bar(x);
baz(x);
}
}
was not made possible. In other words, unless I'm missing something, the above could have been nice and valid syntactic sugar for:
void foo(Iterator<X> it) {
for (X x; it.hasNext();) {
x = it.next();
bar(x);
baz(x);
}
}
