Closes #739
Description
Assignment using the force-move operator gets the current value, and if it is non-nil, aborts the program.
However, when the force-move operator is used in an initializer to initialize a field, getting the value will naturally result in no value, which is not an implementation error like in all other cases (e.g. in a non-initializer like a function).
