This is my idea

```nohighlight
task=@task begin
while true
sleep(1)
foo()
if should_end
    # ?
end
end
end

```

But

1. are there any simple ways to contact other than using `global should_end`?
2. how to end the task from inside the expression?

P.S.  
The problem is solved in an answer in stackoverflow.

You mean repeatedly calling a function until some condition is met? You may want to look into [`Timer`](https://docs.julialang.org/en/v1/base/base/#Base.Timer-Tuple%7BFunction,%20Real%7D).
