Indexed Access Types
Thank you! Good question... I've been looking at this for so long I can't remember 😂 Let me give a more detailed example: I'm trying to create a type to be used to validate the payload in a search request. I've landed on this as the implementation 
const status = ["Available", "Unavailable", "Sold"] as const;
const size = [
  { label: "Big", value: "100kg" },
  { label: "Small", value: "10kg" },
] as const;

const searchPayload = type({
  "page?": "number",
  "sort?": "string",
  filters: {
    "status?": type(["===", ...status]).array(),
    "size?": type(["===", ...size.map((s) => s.value)]).array(),
  },
});

type SearchPayload = typeof searchPayload.infer;
// Evaluates to the type I want
// type SearchPayload = {
//   filters: {
//       status?: ("Available" | "Unavailable" | "Sold")[];
//       size?: ("100kg" | "10kg")[];
//   };
//   page?: number;
//   sort?: string;
// }
const status = ["Available", "Unavailable", "Sold"] as const;
const size = [
  { label: "Big", value: "100kg" },
  { label: "Small", value: "10kg" },
] as const;

const searchPayload = type({
  "page?": "number",
  "sort?": "string",
  filters: {
    "status?": type(["===", ...status]).array(),
    "size?": type(["===", ...size.map((s) => s.value)]).array(),
  },
});

type SearchPayload = typeof searchPayload.infer;
// Evaluates to the type I want
// type SearchPayload = {
//   filters: {
//       status?: ("Available" | "Unavailable" | "Sold")[];
//       size?: ("100kg" | "10kg")[];
//   };
//   page?: number;
//   sort?: string;
// }
I was wondering if there was a cleaner/preferred way to pick out the value prop from the size array with arktype, rather than creating a new array via the map.

Latest "keys:distilled" equivalent?
No problem at all, thank you for the (impressively fast) response! 👍
