>Comments in -- style are too hard to mention cause they do not stop the eye-flow as // vertical slashes do.
That is why I chosen "//"-comments for my Lisp-dialect, after trying "--" and ";;" at first. The ";" is more useful for list-of-lists enumeration (where ;; would be empty element), and "--" just doesnt look right for the job, though it could be used nicely in place of "_".
