I think we agreed to disallow this case as well. Any reason to make an exception here?

This is the case where we want an **alias** to an object that we know lives somewhere already.
This is captured in the style guide already, here's a snippet:

```
// 4: Don't use (since the T that got constructed is a temporary!).
const T& t = T("Hello").member();

// 4: Preferred alias pattern (see below).
const T t("Hello");
const T& t_ = t.member();
```
