Headings of the relevant sections in the specification: ** Detached Modifier Suffix

Feature description
Allows detached modifiers like lists to contain complex Neorg constructs like tags.

- :
  This is part of the list item.
  @code lua
  print("This is also a part of the list item")

  -- Despite the fact that there is a double newline dividing the `print` statement and this
  -- comment, it is not a paragraph break, therefore it does not terminate the slide.
  @end

You can already nest such blocks without using the detached modifier suffix with the current parser. We will need to figure out how to proceed with this.
