For reference, this will do what you're looking for (array starts in
tags_on, key in desired_key):
hash = tags_on.detect { |h| h.has_key?(desired_key) }
result = hash[desired_key] if hash
I've had to build little arrays of single-key hashes like this to work
around 1.8.6 not having ordered hash semantics.
