Exploring Graphs with Elixir: graph_commons/lib/graph_commons/utils.ex p90-92

I have to fully qualify any use of the functions inside GraphCommons.Utils module.

The book states:
iex> "MATCH (n) RETURN n" |> cypher!

I have to use:
iex> “MATCH (n) RETURN n” |> GraphCommons.Utils.cypher!

There is no iex> import GraphCommons.Utils statement in the book and that would rather go against what’s trying to be achieved.

Therefore, a suggestion to clarify how to get to the Utils functions without fully qualifying would be helpful.

thanks
