alt Hacker NewsIf I created a new programming language I would just outright prohibit mutable global variables. They are pure pure pure evil. I can not count how many times I have been pulled in to debug some gnarly crash and the result was, inevitably, a mutable global variable.
You need to be pragmatic and practical. Extra large codebases have controllers/managers that must be accessible by many modules. A single global vs dozens of local references to said “global” makes code less practical.
