Jx

There's something else called JX, which is some extension to J. And well, I peppy cantana is a programmer who writes everything in tacit form. It's amazing to me what he can do in in tacit programming. When the language diverged, when that was taken out, I believe he kept it in his version of J. He was doing financial operations using J and for a while he kept up with it. But I think as J, when I came in, came in and we started pushing the language forward again, I think it hasn't kept up with that.
