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.
