- self 1y agoI think their point is that Elixir lets you write defmodule Multiply do def m9(m1), do: m1 * 9 end # elsewhere... defmodule Caller do def doit() do Multiply.m9(2) Multiply.m9("hi") end end It won't raise an exception or give you a warning while compiling it (tested with 1.18.4). Even adding @spec m9(integer()) :: integer() above its definition doesn't do anything.
