inferring a type

This is something that occurred to me a while ago, and again I was thinking about it last night. I noticed how redundant it seems to type an expression like this:
SomeType x = new SomeType();
I asked myself, why do you have to type SomeType twice? I realize the first is a class name and the second is a constructor, but still it's a little redundant.
Anyway, coincidentally, I found a video on MSDN with Anders speaking about a bunch of things, and he happened to bring up this very point. He said one thing they were considering for C# was this possible syntax:
var x = new SomeType();
and the type of x would be inferred from the 'new' expression. I noticed that the video was posted in 2004, so I'm wondering, is this some feature that has snuck into the language since then? If not, why not?
Thanks. .
