It's not like KDevelop doesn't have very fully featured auto-completion support right now :).

Its existing C++ smarts are extremely impressive already; the developers are mostly considering libclang to get out of having to maintain their own C++ implementation as time goes on and the language gains more features.

Qt creator is good, at least with < 100KLOC projects, probably with ones larger as well.
