Bug 22369 – Unreachable statements in std.concurrency with noreturn values / callbacks

Using std.concurrency with noreturn values, functions, delegates, ... causes multiple "unreachable statement" warnings. ========================================================================== import core.time : Duration; import std.concurrency; void main() { static noreturn foo(int) { throw new Exception(""); } // Rejected due to a different issue // spawn(&foo, 1); // spawnLinked(&foo, 1); receive(&foo); receiveTimeout(Duration.init, &foo); receiveOnly!noreturn(); send(Tid.init, noreturn.init); prioritySend(Tid.init, noreturn.init); yield(noreturn.init); __gshared noreturn n; initOnce!n(noreturn.init); } ========================================================================== std\concurrency.d(2158): Warning: statement is not reachable std\concurrency.d(2748): Warning: statement is not reachable
