ease and intuitiveness ranking: PowerShell, WolframLang, emacs lisp, python, golang. demo it.
both python and golang had to change their walk dir function to improve speed.
emacs lisp and WolframLang, are very different from the industrial langs such as python golang. math langs focus on function aspects, input, output. Static. e.g. sin(x). The non-math langs adds a time concept. This is also the different between math and algorithm. What is, vs how to.
