Solidity Value Types Enums

enum moveChoice { moveLeft, moveRight, moveStraight, stayStill }
    moveChoice currentChoice;
    moveChoice constant defaultChoice = moveChoice.moveStraight;

    function moveGoStraight() {
        choice = moveChoice.moveStraight;
    }

    // Due to enum types not being a part of the ABI, the signature of "getChoice"
    // will be changed to "getChoice() returns (uint8)" automatically
    // for everything external to Solidity. The integer type that was used is simply
    // large enough for holding all enum values, for example, if you have multiple values,
    // `uint16` is going to be used and so on.
    function getChoice() returns (moveChoice) {
        return currentChoice;
    }

    function getDefaultChoice() returns (uint) {
        return uint(defaultChoice);
    }
