I do not see any great sense in this function. In= fact you need to write its realization for each container. So it look= s like the realization of function std:;swap in containers. Moreover std::b= asic_string has already method append. So that to make the call of the= function interchangeable with other containers it is better to make it a c= lass member.
 
Non-member append/push_= back is easily implementable in terms of end() (which is part of Container = concept requirnment since 1998) and insert(...) (which is part of Sequence = concept requirenment since 1998).
Once such function will be implemented= as non-member it would work with any conformant sequence automaticly. That= is not only about STL containers, but also about containers which users de= veloped themself since 1998.
Just look at http://www.boost.org/doc/libs/= 1_54_0/libs/range/doc/html/range/reference/algorithms/new/push_back.html
