+ * A node ec_node_str("foo") will complete with "foo" if the input
+ * contains one token, with the same beginning than "foo":
+ * - [""]
+ * - ["f"]
+ * - ["fo"]
+ * - ["foo"]
+ * But it will not complete:
+ * - []
+ * - ["bar"]
+ * - ["f", ""]
+ * - ["", "f"]
+ *
+ * A node can have child nodes. For instance, a sequence node
+ * ec_node_seq(ec_node_str("foo"), ec_node_str("bar")) will match
+ * ["foo", "bar"].
