It's too magic for my taste.  I've always thought of

  x += n

as exactly swappable for

  x = x + n

(which I think is actually what's going on underneath...?)  and this
would make it pretty impossible to view it that way.

Also, #+ means different things to different objects... so you might
really be calling three entirely different methods.  The same thing is
true if you iterate through them explicitly, of course, but for me
personally doing it implicitly is too, ummmm, implicit.
