I don’t know gleam, but surely

    list.map(fn(line) { line |> calculate_instruction })

Could be written

   list.map(calculate_instruction)

?

You're right, but loads of times I just left that there because I probably did something more involved in the map that I ended up deleting later without realising.

		This sounds like the kind of situation where the LSP could suggest the simpler code, I'll see if there's an issue for it already and suggest it if not.

That is correct.
