Discussion:
LWG has said recently that we don't want public exposition-only things, as that may encourage users to try to use those names (and some implementers to actually use those names).
[2018-06-18 after reflector discussion]
Priority set to 4
Proposed resolution:
This wording is relative to N4741.
Edit 25.6.4 [istreambuf.iterator] as indicated:
namespace std { template<class charT, class traits = char_traits<charT>> class istreambuf_iterator { public: […] using istream_type = basic_istream<charT,traits>;class proxy; // exposition onlyconstexpr istreambuf_iterator() noexcept; […] private: class proxy; // exposition only streambuf_type* sbuf_; // exposition only }; […] }
