That's not the feature he requested.

He's asking for this:

struct Foo {
    auto foo() -> vector<int> *
    { return new vector<int>(); }
};

    auto x = f.foo();
    x->@

This corresponds to the qcompilerdetection.h macro Q_COMPILER_AUTO_FUNCTION.

Also note that C++14 will allow further reducing this to:
    auto foo()
    { return new vector<int>(); }

    auto x = f.foo();
    x->@

I named that feature Q_COMPILER_AUTO_RETURN_TYPE in my branch, but I don't 
like the name. The committee is referring to this feature as "generalised 
lambda" (or something similar, I have to go find the expression) because it is 
similar to what you can do with a lambda:

    auto foo = []() { return new vector<int>(); }
    auto x = foo();
    x->@

In other words, there are two features we're looking for here:
 1) supporting the new style function declaration from C++11
 2) inferring the type from a function body, as in:

    []() { return new vector<int>(); } ()->@

In all the cases above, @ should be showing the expansion of vector<int>.
