Coin 是保留字嗎？

如果我嘗試在 Mix 中編譯以下範常式式碼，它將不起作用。一旦我將名稱從 Coin 更改為 Coins，它就會開始按預期工作？這是錯誤還是功能？

contract Coin {
   // The keyword "public" makes those variables
   // readable from outside.
   address public minter;
   mapping (address => uint) public balances;

   // Events allow light clients to react on
   // changes efficiently.
   event Sent(address from, address to, uint amount);

   // This is the constructor whose code is
   // run only when the contract is created.
   function Coin() {
       minter = msg.sender;
   }
   function mint(address receiver, uint amount) {
       if (msg.sender != minter) return;
       balances[receiver] += amount;
   }
   function send(address receiver, uint amount) {
       if (balances[msg.sender] < amount) return;
       balances[msg.sender] -= amount;
       balances[receiver] += amount;
       Sent(msg.sender, receiver, amount);
   }
}

該Coin合約包含在Solidity 標準庫中——這是概念證明時代的一項功能。標準庫包括以下合約：

• Config,
• Coin,
• CoinReg,
• coin,
• service,
• owned,
• mortal,
• NameReg,
• named,
• std,
• configUser.

目前不鼓勵使用它們，除了owned和mortal。
