  # Because HAML doesn't leave any trace in the nodes when it merges lines that
  # end with a comma, it's harder to assign a node to the second line here:
  # = some_call user,
  #             foo, bar
  # So if the simple strategy (above) doesn't work, we try to see if we check if the last node
  # that was before the requested line was one that could have been merged. If so, we use that one.

  # There are the cases were the merging without traces can happen
