autofac's Func<T> to resolve named service

Question

Given registered services:

builder.RegisterType<Foo1>().Named<IFoo>("one").As<IFoo>();
builder.RegisterType<Foo2>().Named<IFoo>("two").As<IFoo>();
builder.RegisterType<Foo3>().Named<IFoo>("three").As<IFoo>();

Can I retrieve named implementations of IFoo interface by injecting something like Func<string, IFoo> ?

public class SomeClass(Func<string, IFoo> foo) {
    var f = foo("one");
    Debug.Assert(f is Foo1);

    var g = foo("two");
    Debug.Assert(g is Foo2);

    var h = foo("three");
    Debug.Assert(h is Foo3);
}

I know I can do it with Meta<>, but I don't want to use it.

You could register your own resolving delegate like this:

builder.Register<Func<string, object>>(c =>
    {
        var cc = c.Resolve<IComponentContext>();
        return named => cc.Resolve<object>(named);
    });
