I think @gdalle has a good point.

Just to clarify what’s going on though: this is a “world-age issue” which (to my understanding) happens when you define a function that should live in the scope of `Main`, but you defined it within another function. When you now try to call the newly defined function before you are back to `Main`s scope, you get a world-age error.

There is some more detailed discussion [here](https://discourse.julialang.org/t/world-age-problem-explanation/9714/3) and a StackOverflow answer [here](https://stackoverflow.com/a/41288817) which shows the behavior of `include`.
