as pointed out... bits vs bytes... I think the overall idea here is interesting. It is "cheating" because the implicit "EOF" and "start of file" allow us to forego indexing the data. This "cheat" is similar to the technique used in the article.

Similar cheats would be to leverage hardware instructions (imagine if x86 had a "pad with N zeros" instruction that fit in 7 bits). That's still cheating because the information is hiding in the architecture.
