There's a lot of folk workarounds for this problem. They're mostly fine for languages that use ASCII lightly. But it'd be a pretty confusing mess if we applied the "pick something in the jargon file" approach to something like the Hoon syntax.
Everyone who's learned our ASCII dictionary, which admittedly is not a whole lot of people, applies it compulsively.
Hence why geeks and programmers rarely call them by name. See http://www.catb.org/jargon/html/A/ASCII.html .
