Just as a curiosity, I remember 1 - 1.5 yrs ago when I was somewhat active
on this list, it was a big deal when ant finally decided to drop support
for running ant under java 1.1 and allow use of Collections & other 1.2
stuff in the code base. Did you guys move to 1.4 when I wasn't watching
(the last year or so)?

How about (in a java15 package), we have a class that uses reflection to
look for the iterator() operator
Class IterateOver implements Iterable {
Object instance;
IterateOver(instance) {this.instance=instance}
public Iterator iterator() {
Class clazz=instance.getClass();
Method method=clazz.getMethod("iterator");
return method.invoke(instance);
}
}
you could then do (for e:new IterateOver(something));
not ideal, I admit. Oh, there is all that generic typing stuff too. sigh.
