This looks very interesting! Would someone be willing to translate to english? I've only got a vague idea of what is being discussed.

To try and cut to the core of the issue: in Ruby 1.8 it was common practice to use the String class to represent both "proper strings" as well as a "bag-o-bytes". In Ruby 1.9, you can only properly use the String class to represent "proper strings". For a "bag-o-bytes" we're left with Array, but there are times when Array is not the right abstraction (e.g. reading data from a socket, identifying a start and stop token, and writing the bytes between to a file on disk). Also, the "BINARY" encoding is not the right abstraction, because you still have an object which will worry about encodings and, due to Ruby always trying to do "the right thing", bugs can be very difficult to track down. Consider:
