 // TreeNode is generic, ContainerNode-like linked tree data structure.
 // There are a few notable difference between TreeNode and Node:
 //
 //  * Each TreeNode node is NOT ref counted. The user have to retain its lifetime somehow.
 //    FIXME: lifetime management could be parameterized so that ref counted implementations can be used.
 //  * It ASSERT()s invalid input. The callers have to ensure that given parameter is sound.
