nit: Don't we typically place includes above class declarations? (Actually our
coding style guidelines don't specify that, but they do say "Forward
declarations and file includes should be in alphabetical order (but we aren't
very strict about it)," which could be taken to mean they should be
interspersed, but I haven't typically seen that.)

I guess 'c' does come after '#'...
