Nim how to define constructors?

Question

Is there a way in Nim to define constructors for an object? For example I have

type Deck* = ref object
    cards* : array[52, Card]

can I create an empty constructor that creates automatically all the cards?

Answer 1

type
  Card = int
  Deck* = ref object
    cards* : array[52, Card]

proc newDeck: Deck =
  new result
  for i, c in result.cards.mpairs:
    c = i
