Using Python's built-in defaultdict we can easily define a tree data structure:
def tree(): return defaultdict(tree)
That's it!

extractions = {} | |
text.gsub!(%r{<pre>.*?</pre>}m) do |match| | |
md5 = Digest::MD5.hexdigest(match) | |
extractions[md5] = match | |
"{gfm-extraction-#{md5}}" | |
end |

Thanks for pinging me; it's nice to know Typesafe is keeping tabs on this, and I | |

err on the side of giving you too much to think about. I realize I'm being very | |
critical of something in which you've invested a great deal (both financially |
