Eclipse has refactoring told for at least Java and c{,++} Variable renaming respecting scope, function renaming that updates the name at the call sights but ignoring overloads, function extraction... and so on. You may not use it or indeed use eclipse at all. I can't tell you about the details, clearly something going on beyond syntax highlighting via keyword regex matching. With a beefy enough box it all works well enough.
