Look at java.lang.Iterable. It was added to implement forach operator 
and by that JLS indirectly references java.util.Iterator.

I think that in each proposal, there are just few new interfaces added 
in java.lang for facilitating [] access. java.util classes will 
implement those classes, but don't have to mentioned in JLS.

So, [] access is not breaking the java.lang boundaries, unlike already 
existing foreach.
