This would extend to custom functions as well; none of the following functions are in a cycle:

```
@function --x() {
  @media (false) {
    result: --x();
  }
  result: 1px;
}
```

```
@function --y() {
  @if (false) { /* If added in the future */
    result: --y();
  }
  result: 1px;
}
```

```
@function --z() {
  --unused: var(--unused);
  result: 1px;
}
```
