  # Reusable contexts
  #
  # The follow contexts are currently constructed to be reused in the
  # Objetive-C++ syntax. They are specifically constructed to not push into
  # sub-contexts, which ensures that Objective-C++ code isn't accidentally
  # lexed as plain C++.
  #
  # The "unique-*" contexts are additions that C++ makes over C, and thus can
  # be directly reused in Objective-C++ along with contexts from Objective-C
  # and C.
