So rules of thumb, standardizations, and personal preferences are mostly what we have to go by. When code that looks very similar to code you've seen before really *is* similar to code you've seen before, comprehension speed can increase. A study of chess masters' ability to memorize chess positions showed that they were powerfully accurate when shown positions from real games, but no better than the average schmoe when shown randomly positioned pieces. So if everyone basically follows PEP8 we all benefit from playing by the same game rules, as it were. -- Neil Cerutti
