TypeScript Labeled Tuples

[jplante]

With TypeScript 4.0 they have introduced Labeled Tuples:
https://www.typescriptlang.org/docs/handbook/release-notes/typescript-4-0.html#labeled-tuple-elements

The current tuple types in the JSON output from TypeDocs provides the following information about a tuple type:

elements:(2) [{…}, {…}]
  0:{
    type: 'intrinsic', 
    name: 'number'
  }
  1:{
    type: 'intrinsic', 
    name: 'number'
  },
type:'tuple'

As you can see the elements in the tuple do not include their labels.

Before in 3.x your tuple might be:

export type PointAlias = 
  | Point
  | { x: number, y: number }
  | [ number, number ]

This tuple above does not indicate the order of "x,y" or "y,x"

But with 4.x and labeled tuples you can provide:

export type PointAlias  = 
  | Point
  | { x: number, y: number }
  | [ x: number, y: number ]

However currently TypeDoc does not provide that extra meta-data about the tuple types.

I'm somewhat surprised TypeDoc runs at all with 4.x... I worked on adding this and upgrading to 4.x last weekend but ran into issues & what I think is a bug in the latest TS. I'll hopefully have time to build this this weekend.

Support has been released in 0.19.
