So now consider:

    y.a = b,c,d = x.e = wower()

How would you like to rewrite _this_?-)  There is *NO* rewrite
that ensures constant semantics except by introducing _another_
temporary variable -- *yecch*!-)

Seriously now -- multiple assignment is a very minor thing, but
handy when you do need it, and not error-prone.  So, why not?
