experimental c++0x available?

[daviddoria]

I was reading about the new "tuple" type coming in c++0x, and I decided to try it. I saw that if you give a compiler flag -std=c++0x it will work. So I did it, and then #include <tuple> works and everything was good. Then I decided to try the default member initialization.

class Point
{
	public:
		int a = 4;
};

but it doesn't work. Does anyone know where I can find a list of which features are available using -std=c++0x and which are not yet available? I am using gcc.

Thanks,
Dave

The list you are after in in http://gcc.gnu.org/gcc-4.3/cxx0x_status.html

I am assuming that you are using 4.3.

However, I am sligthly mystified , I though that you can only write what you have if you are using static or const. If you have the C++0x reference could you/someone post it please. Many thanks.

This is taken directly from here:

http://en.wikipedia.org/wiki/C%2B%2B0x#Object_construction_improvement

class SomeClass
{
public:
  SomeClass() {}
  explicit SomeClass(int iNewValue) : iValue(iNewValue) {}
 
private:
  int iValue = 5;
};

I don't see range loops at all on that list you sent - is it called something else?
