Linting inside Markdown blocks outside of .md files

Is it possible to get linting inside of Markdown-like blocks inside of non-Markdown files? The use case here is in Elixir documentation, which is formatted in Markdown, but it’s actually just a block inside of a .ex or .exs file.

From the above link, an example:

defmodule MyApp.Hello do
  @moduledoc """
  This is the Hello module.
  """

  @doc """
  Says hello to the given `name`.

  Returns `:ok`.

  ## Examples

      iex> MyApp.Hello.world(:john)
      :ok

  """
  def world(name) do
    IO.puts "hello #{name}"
  end
end

What’s between the """ of @moduledoc and @doc (and also, though not shown, @typedoc) is formatted with Markdown. Getting the warnings and/or, if possible, the auto-formatting inside of those blocks would be tremendous!

Bummer. That’s definitely how I’d want to go about this. I’ll leave the issue open, but please don’t hold your breath. 😃

Here’s a grammar injection approach https://github.com/mjbvz/vscode-comment-tagged-templates.
