i’m a bit confused by #:break in for/fold clauses: > (for/fold ([res 0]) (#:break (= res 5) [i (in-range 10)]) (display i) i) 01234567899 > (for/fold ([res 0]) ([i (in-range 10)] #:break (= res 5)) (display i) i) 0123455 I was expecting the first case to break before i would be bound.

A #:break is like a #:when in that creates nested iteration (in the for* sense) for anything after it. So, your first example is similar to #:when #t: it’s only checked once before the i iteration starts.

I see, thanks. Would it be useful if i add this example to the docs? Or maybe would it make sense to disallow #:break before any clause?
