Discussion:

In Section 21.3.3 [basic.string] the basic_string member function declarations use a consistent style except for the following functions:

>     void push_back(const charT);
>     basic_string& assign(const basic_string&);
>     void swap(basic_string<charT,traits,Allocator>&);

- push_back, assign, swap: missing argument name
- push_back: use of const with charT (i.e. POD type passed by value not by reference - should be charT or const charT& )
- swap: redundant use of template parameters in argument basic_string<charT,traits,Allocator>&

Proposed resolution:

In Section 21.3.3 [basic.string] change the basic_string member function declarations push_back, assign, and swap to:

>     void push_back(charT c);

>     basic_string& assign(const basic_string& str);
>     void swap(basic_string& str);

Rationale:

Although the standard is in general not consistent in declaration style, the basic_string declarations are consistent other than the above. The LWG felt that this was sufficient reason to merit the change.
