numerical code isn't like application code. the rules of application code don't always apply. for example, i think one character variable names are totally fine if they come from equations or papers where in most applications it's generally frowned upon. this is why i'm a little skeptical of languages that blur the lines. sometimes ideas from application programming can complicate numerical code and sometimes numerical programmers don't fully understand the systems abstractions they're building on and end up reinventing wheels to avoid simpler solutions they feared or didn't know existed. the moral of the story is to keep an open mind, to not be a zealot and to avoid dogmatic thinking.
