split_string.rb

def split_string(string, key)
  items = string.value.split(" " + key.value + " ")
  if items.count == 1
    Sass::Script::Bool.new(false)
  else
    Sass::Script::List.new(items, :comma)
  end
end

I get the following error when trying to return the List

The input is the following:

@debug split_string('1 2 3 4 5 at 500px', 'at');

NoMethodError on line 27 of /usr/local/gems/sass-3.2.5/lib/sass/../sass/script/node.rb: undefined method `options=' for "1 2 3 4 5":String
