+ * @brief A node in the abstract syntax tree.

+ * type of the node. The union u is used to store the value of the node
+ * for its given kind. The lhs pointer points to the left hand side of
+ * its child node and the rhs pointer points to the right hand side of
+ * its child node (if any). Or the lhs and rhs pointer are used to
+ * point to the previous and next statement in a linked list (in case
+ * of ASTMT). Additionally, the payload pointer is used to store the
+ * condition of an if-statement and other statements.
