Code

function f(a: number, b: string) : void
{
}

let params : [number, string] = [10, 'test'];

f(...params);

I expect that to compile without any errors.

duplicate of #4130 ?

Looks like it, yes.

This issue came up when thinking about #24240, which has applications in forwarding rest parameters.
