I’m actually a bit confused, I thought unquote can only be used inside a quote block?

I don't understand quote/unquote: why do we need them?

There are two worlds because there are two times when code is executed: At compile time (any code, which is not a function body is executed + macros) At runtime (Function bodies are executed) Take this example: defmodule A do for {i, level} <- %{1 => :err, 2 => :warn, 3 => :info} do def log_level(i), do: level end end For the function log_level what do you expect i and level to represent? Basically it’s 3 times this: def log_level(i), do: level, and it would complain about unmatcha…

You can use unquote in module bodies as well.
