Hi all, personally I'd love to be able to do something like this:

vector<int> v;
v.assign(1, 2, 5, 9, 8, 7) etc

Checkout Boost's Assign Library. You can do these:

vector<int> v;
v += 1,2,3,4,5,6,7,8,9;

Institutionalized obfuscation, anyone? That statement has a
predefined meaning in C++, without any library, and any code
which changes a predefined meaning should be avoided at all
costs.

or

vector<int> v = list_of(1)(2)(3);

That's better. A lot of the time, of course, simply:

    static int const init[] = { 1, 2, 5, 9, 8, 7 } ;
    std::vector< int > v( begin( init ), end( init ) ) ;

is just as good.
