Discussion:
In the current working paper, the <string> header synopsis at the end of
27.4 [string.classes] lists a single operator<< overload
for basic_string.
template<class charT, class traits, class Allocator>
basic_ostream<charT, traits>&
operator<<(basic_ostream<charT, traits>&& os,
const basic_string<charT,traits,Allocator>& str);
The definition in 27.4.4.4 [string.io] lists two:
template<class charT, class traits, class Allocator>
basic_ostream<charT, traits>&
operator<<(basic_ostream<charT, traits>& os,
const basic_string<charT,traits,Allocator>& str);
template<class charT, class traits, class Allocator>
basic_ostream<charT, traits>&
operator<<(basic_ostream<charT, traits>&& os,
const basic_string<charT,traits,Allocator>& str);
I believe the synopsis in 27.4 [string.classes] is correct, and the first of the two signatures in 27.4.4.4 [string.io] should be deleted.
Proposed resolution:
Delete the first of the two signatures in 27.4.4.4 [string.io]:
template<class charT, class traits, class Allocator> basic_ostream<charT, traits>& operator<<(basic_ostream<charT, traits>& os, const basic_string<charT,traits,Allocator>& str);template<class charT, class traits, class Allocator> basic_ostream<charT, traits>& operator<<(basic_ostream<charT, traits>&& os, const basic_string<charT,traits,Allocator>& str);
