It's a strongly pure function. It _is_ nothrow, which means that it won't throw any Exception, and its return value isn't used. assert is more of a debugging tool than anything. Sure, assert(false) sticks around in release mode, but still. Based on the purity and nothrow rules, this function can be optimized out of existance. I really don't see a problem with this. Now, assuming that is indeed the correct behavior, the obviously runnable/test41.d needs to be fixed, but it looks to me like having the call to x optimized out of existance makes perfect sense. And if the assert doesn't get hit, then it doesn't get hit. Asserts are intended primarily for debugging purposes. Yes, it's an assert(false) and not a normal assert, but still, if we start worrying about whether an assert would have killed a function or not, then we won't be able to optimize out functions like this, which wouldn't be good IMHO. Now, assuming that it's really only an issue when you have a strongly pure function where you throw away its return value, then maybe that's not a big deal, because that's bad code on the part of the programmer anyway, but I'm still inclined to think that it makes sense for x to never be called in this code (at least if optimizations are turned on). -- Configure issuemail: http://d.puremagic.com/issues/userprefs.cgi?tab=email ------- You are receiving this mail because: -------
