Hi
I know this is slightly off topic but f there is a discussion on enhancing the
for each loop ...
1 is there any chance that we could use ARM functionality and allow a
ClosableIterator to be introduced. There are many occasions that an iterator is
backed by some resource (list of lines in a file, list of rows in a database)
but there is no mechanism in the foreach loop to close this implicit resource.
This was one thing that C# got right in its implementation, if the iterator
implements IDisposable then it is disposed. In java it may require an
additional interface although I doubt that any current Iterators implement
Closable
2 it would be nice if the foreach loop honoured the RandomAccess semantics but
it is probably too late for that now
