tryCopyFrom(sourceCollection: Collection) lockReceiver, updating;

Dictionary implementations (including the MemberKeyDictionary and DynaDictionary classes) support copying to an ExtKeyDictionary class with compatible keys.

Exception 1312 (Class of value passed to a collection method incompatible with membership) is raised if the member types are not compatible or exception 1000 (Invalid parameter type) for dictionary types if the keys are not compatible.
