Amen, brother. 

Even worse: I recall seeing code somewhere that had a data structure
like this:

{k1: [v1,v2], k2: v3, k3: None, ...}
instead of 
{k1: [v1,v2], k2: [v3], k3: [], ...}

I liked the elegant code example for building a book index. However in
practice the user requirement would be not to have duplicated page
numbers when a word occurs more than once on the same page. If you can
achieve that elegantly, please post it!

Cheers,
John
