I don't know anyone who claims to know the whole of C++.

  Knowing the language itself is not that hard. It's big, but manageable. Obviously there will always be corner cases where you need your language lawyer hat (and the copy of the Standard), but those exist for pretty much any language. The library is more complicated, especially once you get to iostreams and locales. But also less of an issue in this scenario.
