Hi all,

I want to construct a static const vector being the result of concatenation of two other vectors. I was thinking to use boost::push_back, but it takes a container as a lvalue reference as a 1st argument. I could develop the following piece of code

template Container concat(Container const &c, Range cont& r) { Container result = c; return boost::push_back(result, r); }

static const std::vectorstd::string v = concat(v1, v2);

But I wanted to avoid to reinvent the wheel. Currently, I am living with this kind of writing:

static const auto v = [&]{ std::vectorstd::string result = v1; return boost::push_back(result, v2); }();

Does boost libraries offer a better alternative to this construct ?

Something like this: using namespace boost; std::vectorstd::string v = copy_rangestd::string>( join( c, r ) ); Jeff
