Yes, I guess it’s the _ sign?
This works:
Enum.take_random(:ets.match(domain, {:"$1", :"_", :"_"}), 3)
But not if I wite :_

No, :_, :__, :., :..., :<, :>, :==, :! are all valid, You are probably talking about :"$" though. That doesn’t work without the quotes.

If it is only possible to create with quotes, it shouldn’t create any warning. If it indeed creates a warning and is not possible without quotes, please file a bug at GitHub - elixir-lang/elixir: Elixir is a dynamic, functional language for building scalable and maintainable applications · GitHub.

For me :"$" doesn’t create a warning. I’m on Elixir 1.7.3 compiled and running on OTP 21.
