A DESCRIPTION OF THE REQUEST :
The for-each-loop currently only supports arrays and instances of Iterable. There's no reason, why it shouldn't also support the Iterator itself directly.

JUSTIFICATION :
It can be nasty and expensive to wrap an existing iterator with a dummy iterable just to use the nice and handy for each loop.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Iterator it = ...;

for ( Object o : it )
{
}


CUSTOMER SUBMITTED WORKAROUND :
DummyIterable itbl = new DummyIterable( it );
for ( Object o : itbl )
{
}

// or:

while ( it.hasNext() )
{
    Object o = it.next();
}
