Another interesting keyword I found whilst looking at Sather is the once keyword. It is used during iteration some thing along the lines of

for ( int i = 0; i < 10, once(j != null); i++ )

where j !=null is only tested on the first evaluation, and is not checked subequently.

So it's the same as:
    if(j != null)
        for( int i = 0; i < 10; i++ )

Just write:

if (j != null)
  for ( int i = 0; i < 10; i++ )
