Two good points:<p>"One immediately notices that most of the keywords have the same length. This is unlike English programming languages where keywords have greater differences in lengths (e.g. cons, display vs. 建， 出). I do not think this will be a serious readability problem, because even without syntax highlighting, the code above looks very clear to me. This is probably going to be a matter of personal taste.
The code is compact, as the keywords are one or two characters long."
