  Hi, I have started trying nim since last 5 days and I have a small doubt. While I can do

  var mittens: ref = new(Animal)
  mittens.name = "Mittens"
  mittens.species = "P. Leo"
  mittens.age = 10
  Run

  I cannot do mittens.sleep(). Error: type mismatch: got (ref Animal) . What is the way to call a method on a ref. Sorry if it is a very stupid question.

  Your first line looks incorrect, just remove the : ref:

  var mittens = new(Animal)
  mittens.name = "Mittens"
  mittens.species = "P. Leo"
  mittens.age = 10
  Run

  Apart from that I can't tell you much more without seeing your full code.

  You may have to dereference: mittens[].sleep() or define sleep for ref Animal.

  Please refer to the code here : http://nim-by-example.github.io/types/objects/ I am trying to figure out how to run the sleep method on mittens ref object, which the tutorial tells is not allowed.

  Isn't a bug? Should not the dot works as accessing a tuple or object field with implicit deref? None can say it isn't ugly.

  Auto-deref for the first argument works in devel with {.experimental.}.
