break-outside-loop

Flag a break or continue with no enclosing for or while loop. The code parses but always fails at lowering with “break or continue outside loop” — including inside a closure, do-block, or comprehension body defined within a loop, since break cannot cross a function boundary.

break with no loop in sight:

function process(x)
    if x < 0
        break
    end
    x
end

3 |         break
  |         ^^^^^ `break` outside of a `for` or `while` loop

A do-block body is an anonymous function, so the outer loop is out of reach:

for i in 1:3
    foreach(1:2) do x
        continue
    end
end
