  +    Only Dart Sass supports calling `map.merge()` with more than two arguments.
  +  <% end %>

     If `$keys` is not empty, follows the `$keys` to find the nested map targeted
     for merging. If any key in `$keys` is missing from a map or references a value
     that is not a map, sets the value at that key to an empty map.
  
positive.code: 
  <% function 'map.deep-remove($map, $key, $keys...)',
              returns: 'map' do %>
    If `$keys` is empty, returns a copy of `$map` without a value associated with
    `$key`.

    Identical to [`map.merge()`](#merge), except that nested map values are *also*
    recursively merged.
