Because of the name! Nothing else. I've never seen "vector" in programming having this meaning. In OpenGL (GLSL) there were (is) a vector type but I thought of that as dealing with math/graphical vectors, not to store arbitrary data: /* https://www.opengl.org/wiki/Data_Type_(GLSL) */ vec4 someVec; someVec.x + someVec.y; But if I *now* may think about it further, it is not that strange a thought. Emacs was never a minimalist system so I'm not surprised to find anything in it. (Or surprised to think I found something, in this case.) Also, no matter how useful it (Emacs) might be to writers, journalists, and basically anyone who thinks, reads, and writes, I suppose it still has its stronghold with programmers and science people. And linear algebra, isn't that the math discipline which is closest to computer science?
