Oh and Theif^, VC++10 also supported autos. I use them greatly when iterating through containers. Typing out a 40+ letter iterator class gets old really quick. Especially when you have something insane like:
Code: [Select]
std::map<std::string, std::vector<math::vector3D>> StupidContainerClass();

//Iteration would be something like
for(std::map<std::string, std::vector<math::vector3D>>::iterator i = StupidContainerClass.begin() ; i  != StupidContainerClass.end() ; i ++){
}
//This is where auto makes life MUCH easier
for(auto i = StupidContainerClass.begin() ; i  != StupidContainerClass.end() ; i ++){
}

IIRC you can now do something like:

Code: [Select]
std::map<std::string, std::vector<math::vector3D>> StupidContainerClass;

for (auto i : StupidContainerClass)
{
}
(i.e. using foreach and auto together)

Dwarven blood types are not A, B, AB, O but Ale, Wine, Beer, Rum, Whisky and so forth.
It's not an embark so much as seven dwarves having a simultaneous strange mood and going off to build an artifact fortress that menaces with spikes of awesome and hanging rings of death.

Yes, but that only works in 2012 and it's lovely. I really love the foreach functionality.
But I still use VC++2010, so I will have to do with my method, as the c++11 support is more limited.

Just now I learned what you guys are talking about. lol

I really do think auto is a nice addition, not that I would use it that much, but when I do, I will appreciate it.
