You must remember wrong. All v0.x versions had 0-indexing. Moreover, I even have my old, old code from v-0.5 when -1-based indexing was standard.
When can I expect to see minor version numbers incorporated into the DateTime package?
Yet it was a big design mistake that 0.X versions didn’t follow fractional indexing.
It was remarkably farsighted of @simonster to develop 2-based index even before Julia 1.0 came out!
Indices should naturally start from typemin(Int) to permit the largest possible arrays. Julie is inclusive, and size-related discrimination has no place in the language
