  • add code blocks to [try_][pin_]init! macros

@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?

Allow writing `_: { /* any number of statements */ }` in initializers to
run arbitrary code during initialization.

    try_init!(MyStruct {
        _: {
            if check_something() {
                return Err(MyError);
            }
        },
        foo: Foo::new(val),
        _: {
            println!("successfully initialized `MyStruct`");
        },
    })
