Mark Harwood commented on LUCENE-872:
-------------------------------------
I have some reservations about making it even easier for new Lucene users to
write inefficient code.
Iterating all the way across Hits is normally a poor way of achieving something
in Lucene because of the repeated querying going on in the background.
New users already fall into this trap too often and adding this feature will
undoubtedly lure more people into writing bad "for" loops.
