            # File tmp/rubies/ruby-master/lib/syntax_suggest/code_block.rb, line 59
def <=>(other)
  out = current_indent <=> other.current_indent
  return out if out != 0

  # Stable sort
  starts_at <=> other.starts_at
end

This is used for frontier ordering, we are searching from the largest indentation to the smallest. This allows us to populate an array with multiple code blocks then call ‘sort!` on it without having to specify the sorting criteria
