Unicode identifiers make me uncomfortable. I have no idea how I would type that circular one in the "sharp macro" section (short of copying and pasting), and I'm imagining seeing those missing-character boxes all over the place.

I think that example was more tongue-in-cheek than anything (after all, who would want to write their code in reverse). But if you use e.g. the fcitx input on Linux, you can just press Ctrl-Alt-Shift-U, type "circle arrow", and select "↻" (clockwise open circle arrow) from the list. The fuzzy matching is pretty awesome, I hope similar Unicode handling will come to all platforms in the future.
