+@ngdoc error
+@name $parse:isecobj
+@fullName Referencing Object Disallowed
+@description
+
+Occurs when an expression attempts to access the 'Object' object (Root object in JavaScript).
+
+Angular bans access to Object from within expressions since access is a known way to modify
+the behaviour of existing objects.
+
+To resolve this error, avoid Object access.
