-KC3 maps are like Elixir maps, they are key-values enclosed in `%{}` :
-
-```elixir
-ikc3> a = %{id: 1, title: "My title", message: "Hello, world !"}
-%{id: 1,
-  title: "My title",
-  message: "Hello, world !"}
-```
-
-Destructuring works with maps to extract values :
-
-```elixir
-ikc3> %{id: id, title: "My title", message: message} = ^ a
-%{id: 1,
-  title: "My title",
-  message: "Hello, world !"}
-ikc3> id
-1
-ikc3> message
-"Hello, world !"
-```
-
-
-You can use the dot syntax to access map values from a `Sym` key :
-
-```elixir
-ikc3> a = %{id: 1, title: "My title", message: "Hello, world !"}
-%{id: 1,
-  title: "My title",
-  message: "Hello, world !"}
-ikc3> a.id
-1
-ikc3> a.message
-"Hello, world !"
-```
-
-You can also use the `KC3.access` function for the same result :
-
-```elixir
-ikc3> a = %{id: 1, title: "My title", message: "Hello, world !"}
-%{id: 1,
-  title: "My title",
-  message: "Hello, world !"}
-ikc3> access(a, :id)
-1
-ikc3> access(a, :message)
-"Hello, world !"
-```
-
-To update an existing map you can use Map.put like this :
-
-```elixir
-ikc3> a = %{id: 1, title: "My title"}
-%{id: 1,
-  title: "My title"}
-ikc3> a = Map.put(a, :message, "Hello, world !")
-%{id: 1,
-  title: "My title",
-  message: "Hello, world !"}
-```
