Transform quoted elixir code to a code string

Question

I have a situation where I am expecting some quoted elixir code to be an atom. If the wrong quoted code is passed in I want to raise an error and show what the wrong code was.

Simplest way to show what I need is with an example.

quoted_code = quote do: %{}
"%{}" = some_func(quoted_code)

You can achieve this with Macro.to_string/2

Macro.to_string(quote do: %{}) #=> "%{}"

ok I am positive I tried that. Must have missed out a bracket round the quote or something.
