The simplest possible example (I've done this is std.simd)... but if I have a few different loosely related things? My personal most frequent problem case is collision/physics. pos, 't', velocity, intersectionFlag, intersection target pointer, etc.. lots of loosely related stuff, always results in inefficient function calls in some of the hottest code in the engine. DMD does that for you (Walter is the inventor of NRVO). > Which is awesome for returning larger structs, but not good for returning just a couple of unrelated things that will persist as locals in the calling function.
