Is there an elegant way to create and initialize a const std::vector<const T> like const T a[] = { ... } to a fixed (and small) number of values?
I need to call a function frequently which expects a vector<T>, but these values will never change in my case.
In principle I thought of something like
namespace {
conststd::vector<const T> v(??);
}
since v won't be used outside of this compilation unit.

For C++11:
vector<int> luggage_combo = { 1, 2, 3, 4, 5 };
Original answer:
You would either have to wait for C++0x or use something like Boost.Assign to do that.
e.g.:
#include<boost/assign/std/vector.hpp>usingnamespace boost::assign; // bring 'operator+=()' into scopevector<int> v;
v += 1,2,3,4,5;
