I have no ideas how macros work, but this is very useful and I made a string version also:

  defmacro sigil_d({:<<>>, _line, [string]}, []) do
    spec =
      string
      |> String.split()
      |> Stream.map(&String.to_atom/1) # how could we do without this?
      |> Enum.map(&{to_string(&1), {&1, [], nil}})

    {:%{}, [], spec}
  end

Works great! (so far)

iex(31)> ~d(a) = %{"a" => 5}
%{"a" => 5}
iex(32)> a
5
