32// Recall that in general, compilers without partial specialization
33// can't strip constness.  Consider counting_iterator, which normally
34// passes a const Value to iterator_facade.  As a result, any code
35// which makes a std::vector of the iterator's value_type will fail
36// when its allocator declares functions overloaded on reference and
37// const_reference (the same type).
38//
39// Furthermore, Borland 5.5.1 drops constness in enough ways that we
40// end up using a proxy for operator[] when we otherwise shouldn't.
41// Using reference constness gives it an extra hint that it can
42// return the value_type from operator[] directly, but is not
43// strictly necessary.  Not sure how best to resolve this one.
