> why do you prefer parenthesis-less function calls?

I don’t feel strongly about it, but you gotta admit that this is remarkably easy on the eyes yet also easy to follow:

    parts = version_string.to_s.split(”.”).map(&:to_i)

The Elixir equivalent, likely a series of pipes, would be just as easy to follow but substantially more to read, more symbols to parse etc. I don’t feel like this here line of Ruby makes any sacrifices in understandability compared to this Elixir port we’re both imagining.

Good point about grepping though.

Huh?

  [major, minor, patch] =
    version_string
    |> String.split(".")
    |> Enum.map(&String.to_integer/1)

I don't know that I'd call this "substantially more" of anything.

Enum.map(&String.to_integer/1)

.map(&:to_i)

To me the latter is no less clear so yeah, substantially more.

For context I write Elixir once a week and Ruby once a decade. In particular in this case elixir’s (and erlang’s) arity disambiguation (the slash) seems like unhelpful noise. Enum.map only accepts single-arity functions so it seems weird to me that the language couldn't figure that out for me.
