# `syntax.unexpected_token`

Something else was expected here.

Area 1, [Project layout and modules](../topics/project-layout-and-modules.md); not declinable; the next step is usually the agent's.

```jadpo
type Count = Int {
    min: 0
}

function f(x: Count -> Count {
    return x
}
```

```text

  |                     ^^ expected `)` before `->`
  |           - opened here
  reason: The parameters end with `)`, before `fails`, `->` or the body.
  next: Add `)` after `Count` (agent)
