> But as I used Julia over time, I regularly encountered situations in which it was really frustrating and enacted a mental tax. The opposite never happens. The opposite would be true for a large swath of people coming from scientific computing backgrounds if Julia defaulted to 0-based indexes. That said, in my experience people doing scientific computing have a poorly calibrated sense of what constitutes “hard.” I’m sure plenty of breakthroughs born of brilliant and horrifying code were created over sleepless weekends by grad students who didn’t understand that what they wanted to do was a mental tax. I guess I don’t hear a lot of people doing scientific computing complain about indexing schemes. I prefer 1-based indexes, but 0-based indexes is a small and trivial issue in my list of grievances against, say, Python.
