+* TODO #33 : Handling of partially constructed object               :ANOMALY:
+
+** State
+
+Support of partially constructed object needs special code to handle it 
+correctly (register a correct cleanup function in case of exception).
+
+Current containers don't support such features.
+
+** Actions
+
+Add such support in M*LIB containers. 
+
+It can be difficult. For example, for array _init_set
+function due to the copy of the object one per one. Each copied sub object
+may throw an exception, so we always need to have the container in a correct
+state so that it can be cleanup.
