================
Comment at: include/clang/Lex/TokenLexer.h:169
+  bool PasteTokens(Token &Tok,
+                   llvm::ArrayRef<Token> AltTokens = llvm::ArrayRef<Token>(),
+                   unsigned int *const AltCurTokenIdx = nullptr);
----------------
I think `llvm::ArrayRef<Token>()` can just be `llvm::None`.
