Variable addition (scope issue)

New to Julia

I have the following code, and it is not working. Why is this?

s = 0
for i = 1:2
    s += i/2
end
2

use global s

You haven’t read the scope docs!

s = 0
for i = 1:2
    global s += i/2
end

Note that this is a controversial new feature of 1.0: https://github.com/JuliaLang/julia/issues/28789
