In Elixir this bug is fixed

Can you show what you’re actually trying to do? If you want a collection that emits an infinite number of values there is Stream.repeatedly. Beyond that, this feels like an X / Y problem.

We know what it is, but we don’t know your use case. With an actual use case we might come up with a good solution instead of mimicking something from another language.

def infinite(list \\ []) do
  [infinite(list)]
end

infinite()

Just for fun. Didn’t test it. It will take infinite time before it returns. And I expect the output to be 42.

Closest thing I can think of would be a function that is infinitely callable, like this:

f = fn g -> fn -> g.(g) end end

h = f.(f)

h.().().().().().().().().()
