This means that you use globals with internal linkage instead of external, local variables rather than globals, hide class-related constants inside it’s scope, and so on. If function is only called inside particular function, it should become a nested function. Most of these rely on the language support. Go has quite simple model of scopes and symbol visibility. User-defined identifier can be local or package-local (global).
