Definitely agree that having the inclusive syntax makes sense either way (..= was mildly jarring at first but makes complete sense syntactically) - I just mean the exclusive ranges arriving at that compiler error definitely seems unexpected

Ah! Yeah, I mean maybe. At the same time, special cases can make things harder to understand. This would also technically be a breaking change, though probably not changing any realistic programs.
