The problem is that the delegate get executed an impredictable number of time. Which make side effect extremely hard to handle (I ended up using map.array.filter most of the time in my own codebase) in terms of side-effect or performance. Additionally, the problem is dependent of the inner implementation of both map and filter, which should stay unknown for the user. -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
