that is a bit of an extreme simplification of what I was saying, but I do believe that programming has become a modern day blue-colar job where IMHO the majority of programmers display a lot of creativity when it comes to perverting good ideas. In that context, I think that it makes sense to rescue code from the programmers writing it. I have seen a lot of bad VBA code written using WITH blocks. I just realized that my problem with this thread is the reference to VBA. The concept of method cascades described in: https://gist.github.com/erica/6794d48d917e2084d6ed <https://gist.github.com/erica/6794d48d917e2084d6ed> is partially interesting to me. IMHO a solution allowing the following WITH self { .doSomething() // a lot of code … …. ….. // and 700 lines of code later .doSeomthingElse() } is barking up the wrong tree, because for as grotesque as this code is, if it can be done, it will be done… a lot .. because it is easy to do. And code like the following is IMHO taking the same slippery slope sharedName = newValue // myInstance.sharedName = newValue (3) _.sharedName = newValue // the locally scoped newValue (2) _._.sharedName = newValue // I don't actually propose this, but (1) The following code however looks like a real productivity improvement (provided NOTHING else can be added between the chained invocations) with let task = NSTask() { launchPath = "/usr/bin/mdfind" arguments = ["kMDItemDisplayName == *.playground"] standardOutput = pipe launch() waitUntilExit() } Cheers LM/
