Hello.
Today I was thinking about Java. Specifically, java.util.Iterator and
the pattern
while(iter.hasNext()) {
Object item = iter.next();
if(predicate(item)) {
iter.remove();
}
}
You can do this in Java.
You can do this just as easy in dcollections:
foreach(bool doRemove, item; container)
{
doRemove = predicate(item);
}
In fact, this little feature is one of the major reasons I wanted to
create a collections library. Tango's container library was modeled after
Doug Lea's (not the Java adaptation of it), and it did not include a way
to remove during iteration.
