Tuple spread

[goodmind]

It's possibly to better open TypeScript issue, but since you added tuple length support I ask here.

const func = (x, y) => x + y;
const payload: [number, number] = [1, 2];
payload.length // 2
func(...payload);
// Expected 2 arguments, but got 0 or more.

Is this supposed to error even if we know tuple's length?

@goodmind: This bug was reported at microsoft/TypeScript#4130 -- I tried a fix at microsoft/TypeScript#18004, though it was considered too hacky.
