Genetic Algorithms in Elixir: Use the capture operator fully
&Enum.sum(&1) is more commonly written as &Enum.sum/1
This is used in a large number of examples.

While we’re talking about minor syntax stuff, how about:
[h1 ++ t2 | [h2 ++ t1 | acc]]

[h1 ++ t2, h2 ++ t1 | acc]

Appreciate this! There’s definitely strange syntactic stuff like that sprinkled throughout. If you or anybody else on this thread sees code like this throughout the book that can be expressed more succinctly/clearly/etc. please feel free to let me know.

Hi there! Not sure if this is the best thread for this, and it’s also very minor and a matter of personal preference 
The code:
|> Enum.sort_by(fitness_function, &>=/2)
is used a handful of times throughout the book. I find it a bit clearer to use:
|> Enum.sort_by(fitness_function, :desc)
but again, purely personal preference
