Inference from rest parameters has strange inconsistent results

[DanielRosenwasser]

declare function foo(...x: readonly any[]): any

type FooParams = Parameters<typeof foo>;

declare function bar(...x: readonly number[]): any

type BarParams = Parameters<typeof bar>

Expected:

• FooParams is any[] or readonly any[]
• BarParams is number[] or readonly number[]

Actual

• FooParams is unknown[]
• BarParams is never
