GNU C++ already provides some features of the upcoming c++0x standard which really make programming more convenient...

// compile with g++ -Wall -std=c++0x newcpp.cpp 
// taken from c't 2010/7
// see also http://gcc.gnu.org/projects/cxx0x.html

#include <vector>
#include <iostream>
#include <initializer_list>
#include <tuple>

struct X {
  // initializer list
  X(std::initializer_list<int> l) : data(new int[l.size()]) {
    std::copy(l.begin(), l.end(), data);
  }
  // disable copy constructor
  X(const X &o) = delete;
  // make explicit that we use the default assignment operator
  X& operator=(const X &o) = default;
  int *data;
};

/* not yet
constexpr int f() {
  return 42;
}
*/

int main() {
  // initializer lists
  std::vector<int> v = {1, 2, 3};
  X x({1, 2, 3});
  
  // auto type
  for (auto i = v.begin(); i != v.end(); i++) {
    std::cout << *i << std::endl;
  }

  /* not yet
  for (const auto i : {1, 2, 3}) cout << i << endl;
  */

  // enum with scope
  enum class Color {Red, Green, Blue};
  enum class Alert {Red, Yellow, Green};
  
  // enum with explicit type
  enum class Level : short {Low = 3, High = 8};
  
  /* not yet
  // null pointer
  int *a = nullptr;
  */
  
  // compile-time assert
  static_assert(sizeof(int *) == 4, "32bit pointers expected");
  
  // tuple (using variadic template parameters internally)
  std::tuple<int, int, int> y{1, 2, 3};
}

OpenURL COinS facilitates the import of bibliographic data shown on a web page in services such as CiteULike or Mendeley.

COinS is short for ContextObjects in Spans; it allows to embed bibliographic metadata in HTML.

OpenURL COinS metadata will soon be available on the wavelab publications page.

Here are links to my CiteULike and Mendeley accounts. Not sure if this online services scale to 6000+ bibliographic entries and 3+ GB of PDF I currently have...
