Usually that also works, but may fail in more complex situations where `user` has a chance of being overwritten between the moments of asking and running `() => user.loginOk()`.

|

Usually that also works and looks good.
|

|

It's a bit less reliable though in more complex situations where `user` variable might change *after* `askPassword` is called, but *before* the visitor answers and calls `() => user.loginOk()`.
