I think so? It's not being modified in the second case because
the array is being passed by value... "x" there is a reference to
an element of the copy created to be passed to each(). I assume
there's a good reason why ranges in general are passed by value
into these functions -- except in this one case, the stuff inside
range types copied when passed by value won't be whole arrays,
I'm guessing.
