def autocorrect_action(node)
  # We can't use the instance variable inside the lambda. That would
  # just give each lambda the same reference and they would all get
  # the last value of @column_delta. A local variable fixes the
  # problem.
  column_delta = @column_delta

  @corrections << lambda do |corrector|
    expr = node.loc.expression
    if column_delta > 0
