That’s a great question! Agree this does need to be clarified in the spec. Because this example is valid syntax as far as I know; `{simpleShadow}` resolves to a complete, correct token type thus this should work.

But we do need to be explicit about the boundaries of this, e.g.:

```jsonc
    "$value": [
      "{layeredShadow}",
      {
        // …
```

If aliasing an array, do the arrays [flatten](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/flat) together?

Further, does the `gradient` type allow aliasing like this, since that also has array values?

This is worth clarifying; I’ll add it to the TODO items for gradients.
