2.2.9

Keep tuple elements around defaults in .in and .out

Combining a tuple's defaultable elements with its other elements dropped some of them, depending on key order:

const T = type(["string", "number = 5", "boolean?"])
// was: [string, boolean?]
// now: [string, number?, boolean?]
T.in.expression
// was: number[]
// now: [number, string, ...number[]]
type(["number", "string = 'foo'", "...", "number[]"]).out.expression

A bound that narrows two existing length constraints at once also no longer throws "multiple distinct intersection results":

// was: throws
// now: string == 2
type("1 <= string <= 2").and("string >= 2")

Thanks to @​ybai08 (#1696).

Reject NaN in unions discriminated by typeof

number rejects NaN, but compiled unions like number | null dropped that check when they discriminated by typeof, so NaN was only rejected with jitless (#1702).

const T = type("number | null")
// was: NaN
// now: ArkErrors: must be a number (was NaN)
T(NaN)

Thanks to @​thecotne.

Don't treat Object.prototype keys as declared

Inherited names like toString or constructor, and an own __proto__ key like the one JSON.parse creates, were treated as declared keys, so "+": "delete" kept them and "+": "reject" accepted them (#1701).

const T = type({ a: "string", "+": "reject" })
// was: { a: "x", constructor: 1 }
