大家在进行C/C++编程的时候，常常定义一些枚举类型的数据，例如：
typedef enum TOKENID
{
TID_ARGS,
TID_MAKEREFANY
} TOKENID;
然后在展示或者处理的过程中又要使用和此枚举相关的一些信息。如：
const TOKINFO m_rgTokenInfo[TID_NUMTOKENS] = {
{L"__arglist" ,TFF_MSKEYWORD | TFF_TERM...},
{L"__makeref" , TFF_MSKEYWORD | TFF_TERM...}
};
一种机制
就是使用字典来解决，这样就需要手工保证两边加入的一致性。另一种更好的
解决方案是使用Macro来解决：
1、宏使用的定义
2、枚举定义
3、信息相关定义。
Mircrosoft在Rotor的C＃编译器使用的一个例子：
1、宏使用的定义
// ===========================================================================
// File: tokens.h
//
// This header defines our token set. Names, ID's, and other valuable per-token
// information is kept here. To pull out significant pieces of each entry,
// define TOK appropriately before including this file.
//
// Name Token ID Flags Predefined type Statement parse routine Binary operator Unary operator Self operator Token Color (end)
// ===========================================================================
#if !defined(TOK)
#error Must define TOK macro before including tokens.h
