I am unclear on why they switch from | to \ for the no argument case, but I don't find it especially ugly.

  I guess Citrine's creator feels the same way.

    Inconsistent = Ugly

      While there are certainly ugly inconsistencies, I disagree that this holds as a rule. This kind of inconsistency - sensitivity of a surface feature to some other attributes of the situation - has the effect of increasing the redundancy of the encoding. Redundancy can (it doesn't always!) help with comprehension and correctness; individual instances should be evaluated on their merits.

  It's documented. There's a visual clue: see the arguments as books on a shelf and the pipe | as a bookend, when you remove the books, the bookend falls over - it's a visual thing and it's my attempt to use humor, so dont invite me to any parties.
