Description

type
  Room = ref object # reference to an object, useful for big objects or
    windows: int    # objects inside objects
    doors: int = 1  # Change the default value of a field (since Nim 2.0)
  House = object
    address: string  
    rooms: seq[Room]

var
  defaultHouse = House() # initialize with default values
  defaultRoom = new Room() # create new instance of ref object
  sesameHouse = House(address: "123 Sesame St.", rooms: @[defaultRoom])

This piece of code produces an error, more specifically it says you can create a new isntance of ref object using

defaultRoom = new Room() --> but this produces an error

Error: type mismatch
Expression: new Room(doors: 1)
  [1] Room(doors: 1): Room

Expected one of (first mismatch at [position]):
[1] proc new(t: typedesc): auto
[1] proc new[T](a: var ref T)
  expression 'Room(doors: 1)' is immutable, not 'var'
[1] proc new[T](a: var ref T; finalizer: proc (x: ref T) {.nimcall.})
  expression 'Room(doors: 1)' is immutable, not 'var'

Wrong repo https://github.com/adambard/learnxinyminutes-docs/issues/new

The code should be new Room or better yet Room()

@beef331 thanks, should I recreate the mistake in the correct repo?

Seems they prefer a PR to fix the incorrect code.
