+// when its allocator declares functions overloaded on reference and
+// const_reference (the same type).
+//
+// Furthermore, Borland 5.5.1 drops constness in enough ways that we
+// end up using a proxy for operator[] when we otherwise shouldn't.
+// Using reference constness gives it an extra hint that it can
+// return the value_type from operator[] directly, but is not
+// strictly necessary.  Not sure how best to resolve this one.
