Think about passing some ambient context around. In Go, you do it by sticking an additional "ctx context.Context" parameter in every single function that conceivably may use it directly or indirectly, i.e. may call some other function that may or may not use it.

And sometimes you need to set up a derived context for one function call, but continue to use the previous one in other calls:

    func Foo(ctx context.Context, ...) {
        Bar1(ctx, ...)
        derived := makeDerivedContext(ctx)
        Bar2(derived, ...)
        Bar3(ctx, ...)
        // ...
    }

It's not hard, but just extremely tedious, esp. if context is mostly utilized in the leaf functions, and the most of the rest of your code simply passes it around.

That's where dynamic scoping enters in.
