Description
This is likely too close to Generics support, but we could use some way to define arrays with fixed element count and types.
Typescript does it with tuple types:
type StringNumberPair = [string, number];
function doSomething(pair: StringNumberPair) {
const a = pair[0];
// ^ const a: string
const b = pair[1];
// ^ const b: number
// ...
}
doSomething(["hello", 42]);
I think the syntax here could be the same as Typescript's.

Research direction
Start by reviewing the existing Generics support, since the issue identifies tuple types as closely related to it. The work is done when the proposed TypeScript-style syntax supports fixed-length elements with distinct types and indexed access reflects those types, as shown in the example.
