> I highly recommend that all programmers learn J. Really? How well? I played with J over a weekend and familiarised myself with the gist of its philosophy, some time ago; enough to know how much time it might take to learn J well. But I stopped quite quickly when I realised how much time it would take to master. It's not impossible and the learning curve isn't too steep, you can piece knowledge together quite nicely (I think) but that curve is very long. I'm glad J exists but I'd really like someone to explain to me why, and in a lot of detail, I should learn it if they are going to make that suggestion.
