I like to live unsafe

If you made it static, sure, but right now you're living compiler error

oh well, I'm just starting to learn the language and come from java, so I thought: wait, it can't be static

const is more like C++ constexpr, but static is similar to static from C: it's a variable that lives outside any scope. Of course, that means the same static can be accessed by multiple threads, so writing to a static is unsafe (except for types like Mutex, you can safely use those to write, but your static won't be declared mut)
