It is worth noting that Fortran, MATLAB, Mathematica / Wolfram Language are all 1-indexed. These are, by far, the most influential and widely-used languages in numerical and mathematical programming for the past ~60 years.
I thought that Julia was aiming for Python's niche, i.e. good at numerical stuff, but also decent at inter-operating with other languages.
Argh. We were so close to leaving 1-based indexing behind as a historical relic. But now it seems we'll be stuck with it for a while longer. I'm not saying we can do anything about it now. I just want someone to validate my frustration :-)
