* Replaced std::exit() with return llvm::Expected/llvm::Error<T> for expected errors like invalid syntax. * Use llvm::formatv() for formatting lexer error messages. x * Addresed merge errors. * Fixed impl scope. * Made ErrorBuilder::operator<< nodiscard, to catch code forgetting 'return' in 'return FATAL_COMPILATION_ERROR()'. * FatalComplationError() -> ParseAndLexContext::RecordLexerError(). Other usages of ERROR_TOKEN in lexer.lpp were actually supposed to be END_OF_FILE. * Update executable_semantics/syntax/parse_and_lex_context.h Co-authored-by: Jon Meow <jperkins@google.com> * Code review fixes. * Update executable_semantics/syntax/parser.ypp Co-authored-by: Jon Meow <jperkins@google.com> * More code review fixes. * Update executable_semantics/interpreter/type_checker.h Co-authored-by: Jon Meow <jperkins@google.com> * Yet more code review fixes... * Update executable_semantics/syntax/lexer.lpp Co-authored-by: Jon Meow <jperkins@google.com> * code review comments * Update executable_semantics/interpreter/interpreter.cpp Co-authored-by: Geoff Romer <gromer@google.com> * Apply suggestions from code review Co-authored-by: Jon Meow <jperkins@google.com> * Update executable_semantics/syntax/lexer.lpp Co-authored-by: Jon Meow <jperkins@google.com> * code review * code review * Apply suggestions from code review Co-authored-by: Jon Meow <jperkins@google.com> * formatted code * review comments * Switched to the new ErrorOr<V> error implementation * code review comments * fixed comment * restored ostream.h as #976 makes the change unnecesary * review comments Co-authored-by: Jon Meow <jperkins@google.com> Co-authored-by: Geoff Romer <gromer@google.com>
