maya,mel,eval,stringarray

mel里，当要eval("client()"),并且要传递stirngarray参数给函数client()时，正确的写法应该是：

global proc intermediator_good(string $array[])
{
    print(">intermediator(): ["+stringArrayToString($array, ",")+"], size="+size($array)+"\n");

    if( size($array) == 0 ){
        $cmd = "client({})";
    }else{  
        $cmd = "client({\""+stringArrayToString($array,"\", \"")+"\"})";
    }
    eval $cmd;
}

要命的是，如果误写成：

global proc intermediator(string $array[])
{
    print(">intermediator(): ["+stringArrayToString($array, ",")+"], size="+size($array)+"\n");

    $cmd = "client({\""+stringArrayToString($array,"\", \"")+"\"}) \n";
    eval $cmd;
}

在client()里:

global proc client(string $array[])
{
    print(">client(): ["+stringArrayToString($array, ",")+"]\n");
}

对于$array={""}和$array={}两种情况，print出来的信息是一样的（都是[]）。调试的时候会被误导
