Symbol properties rendered as strings

Search terms

Symbol property, computed property name, string

Expected Behavior

Render computed properties in some way that looks like TypeScript syntax.

Actual Behavior

Renders computed properties as string literals in signatures, both at the type level and member level:

interface Arrayish<T> {
    "[iterator]"(): IterableIterator<T>;
    length: number;
    slice: (start?: number, end?: number) => Arrayish<T>;
    readonly [index: number]: T;
}

Steps to reproduce the bug

Run TypeDoc on this code:

export interface Arrayish<T> {
  readonly [index: number]: T;
  readonly length: number;
  [Symbol.iterator](): IterableIterator<T>;
  slice: (start?: number, end?: number) => Arrayish<T>;
}
