Before I forget again on how to bind the whole match subject in case statement in Elixir:
"state" as fn argument name and "state" in case surely are having the different scope, that's just I wanted to have the same name saying "state" :).
def to_string(coordinate) do
I thought I'd write it in a way that I would not call the wrapping functions on Agent for each interpolated field, plus would avoid changing to_string implementation with every struct change.
By the way, new cool link for learning Elixir:
Also, just in time for reading the book mentioned above comes an article from Saša Jurić:
To spawn, or not to spawn? Definitely going to validate the book suggested solution/architecture with what Saša Jurić is writing.
Done with learning for today, back to creating some added value to my customers!
