[abecedarius]

Thanks, I think I'll review this -- it's been many years since I looked at Slate.

There's an idea from Fortress (I think?) of squeezing out spaces to express tighter grouping -- that at least struck me as promising.

Yeah, Fortress had a lot of good ideas that we were looking at. We toyed with a way to render and enter unicode operator characters using angle tag notation a la "<circle-plus>". The whitespace idea is interesting but a little dangerous; I think we just need to be able to separate the syntax from the viewer and editor interactions.
