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
# File 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
