I was wondering about that as well. I didn't realize that there was a point
where foreach() already existed and this effectively final tweak was added.
I don't see a relevant JEP, did it predate the JEP process?

D'oh, yes of course... easy to fix though.

Here are the new stats - these look more like what one might expect:

  87 METHODDEF
  11 FORLOOP
   3 TRY
   3 IF
   3 FOREACHLOOP
   3 DOLOOP
   2 WHILELOOP
   1 CASE

Now there are 3 FOREACHLOOP's :)
