Allow writing `_: { /* any number of statements */ }` in initializers to
run arbitrary code during initialization. It also allows declaring
values that can be used later in the initializer:

    init!(MyStruct {
        _: {
            let val = if check_something() {
                42
            } else {
                0
            };
        },
        foo: Foo::new(val),
    })

@Darksonn in your proposal you said that only super let bindings would persist between different {} scopes in intializers. At the moment, this implements that behavior for normal let bindings. Any thoughts on that?
