When I was looking at the page, I noticed that the example:

{

  key: "value",

  dr_nic: "The Comedian",

  ttl: 42

}

didn't seem to use the :symbols I know but omitted the colon.

Turns out, it somehow works:

> a = {my_key: "my_value"}

=> {:my_key=>"my_value"}

Has this always been there? It's kinda weird because that way they look like regular variables O_o
