World age problems when using @everywhere in a function
I have a julia file that is structured something like this:
```julia
using Distributed
function main()
@everywhere variable = [0, 1, 2, 3, 4, 5]
for x in variable
println(x^2)
end
end
main()
```
From my understanding `@everywhere` should define the variable on every worker, including the main process.
But when I run the code, it give me this error:
```UndefVarError: `variable` not defined in `Main`
The binding may be too new: running in world age 38716, while current world is 38717.```
In a jupyter notebook, I can run main() again a second time, and then it works, since I assume then the world age matches...
Can someone explain what is going on and if there is some way to circumvent this problem? I can fix it by defining it again in the main process `variable = [0, 1, 2, 3, 4, 5]`, or by taking the code out of the main() function but to me that doesn't feel intended.
