It's slightly interesting to me that neither object-oriented nor functional-in-the-Backus-sense languages are represented here.

FP, I suppose I can understand, since ML started off with a plethora of discrete features, and things have only grown from there. Great paradigm, but not exactly something you'd want to even try to cram into a single file. But I might have expected to see some sort of Smalltalk- or Io-inspired language in the list.
