As I understand it Julia changed course and is attempting to support arbitrary index ranges, a feature which Fortran enjoys. (I'm not clear on the details as I don't use either of them.)
There was no change of course. Julia's AbstractArray interface requirements are just agnostic about array start indices. we have packages (e.g. OffsetArrays.jl) for arbitrary index ranges and that has existed for a long time.
If anything, the only significant change is that the community is becoming more and more convinced that offset array support is a bit of a footgun and makes it easy for bugs to sneak into generic code.
Let’s hope that they don’t also replicate ISO Fortran’s design flaws with lower array bounds, which contain enough pitfalls and portability problems that I don’t recommend their use.
I haven't used either language much myself and I thought the feature looked brilliant so I'd be very curious to know what sort of issues you ran into in practice.
