My background is scientific and systems programming in C and C++. Currently I write a lot of Python for my job and a lot of Rust for my spare time hobby programming, which consists of things like writing a BLAS, reimplementing other C and C++ projects, etc. So I haven't only programmed in dynamic or scripting languages. I strongly disagree with the assertion regarding single letter variables. I would gently correct a junior programmer who tried to do that and I would chew the hell out of a senior programmer if he tried it. In any language.
