no? you just need to take a &'a str in set_path

I use set_path() to set values in a global static mutable variable. Maybe I could create a &'static str variable inside main() containing the return value and pass it to set_path() ?

I'd still refactor code without using mutable statics, but you can make a Box<str> and then leak it to get a &'static str
