In my theory of "human-readability", odd double tokens like :: can exist successfully so long as there is sufficient utility and logic in the single token :

Tokens are inseparable from human instincts of single = less, double = more and the corresponding emotions: single=less=easier=quicker, double=more=complicated=longer=difficult

If you are not emphasizing the single token as them most common, it's going to cause confusion.
