The 1-based indexing is a smaller deal than people make it out to be. If you're doing scientific computing, it's very unlikely you'll be doing too many fidgety things with indexes anyway. I switch between Julia and numpy with ease. The REPL is on par with ipython (perhaps even better). Also are some IDEs for it but they aren't quite there yet.
