public:
  enum ErrorCode : unsigned char {
    kInvalidExpressionSyntax,

  };

  llvm::ArrayRef<DiagnosticDetail> GetDetails() const override { return m_detail; }
  
  std::error_code convertToErrorCode() const override { return llvm::inconvertibleErrorCode(); }

  std::unique_ptr<CloneableError> Clone() const override { return std::make_unique<cloneableError>(m_message, m_detail); }

  // Implement similarly to ExpressionError
  std::string message() const override;
  void log(llvm::raw_ostream &OS) const override;
