It seems to localize single variables but not arrays. I could even
implement an async that I could interrupt by updating values in a global
array. I actually don't know of any sane way to do this, i.e., interrupt a
task or an async bloc from the main thread?
global x = zeros(1)
@async begin
for i = 1:6
if x[1] > 0
break
end
println("hi $x")
sleep(5)
end
end
then it starts outputting
hi [0.0]
Task (queued) @0x00000001089daf80
hi [0.0]
then once I input
> x[1] = 1
it stops. the async block can also as it runs update the entries of a
global array, so that the global array has different values that you can
access from the interpreter at different times as the async block is
running; this is one way I found to do something like a background task,
and unfortunately I don't know of any sane way to do that in Julia either.
Is there?
