Personally, I think that it's by far the best approach to just do int foo(int i) { int j; return foo(i, j); } It's clean, and I really don't see a big problem with it. But if you _really_ don't want to do that, you can always create a dummy variable and do something like int dummy; int foo(int i, out int j = dummy) { ... } But I'd advise against it, since it strikes me as rather messy, and I really don't see any problem with just creating a wrapper function. It's the kind of thing that you already have to pretty much any time that you try and have a function accept const ref for an efficiency boost, since ref doesn't accept rvalues. A bit annoying perhaps, but not a big deal. - Jonathan M Davis
