Since upgrading to Xcode 4.3, I find myself checking in code that has forward references to methods within an @implementation block. It's very easy to do this without explicitly intending to. I like not having to forward-declare methods anymore, but it causes errors for people who try to build the project using Xcode 4.2.
How are other projects dealing with this? It seems like the options are
(a) Upgrade the project requirements to Xcode 4.3; or
(b) Enable some hypothetical compiler flag that will re-enable the forward-reference errors (is there one?)
