Assigning to a member of an uninitialized optional does not initialize the object before assigning to it. This resulted in the AddressSanitizer detecting attempt to double-free when the uninitialized string contained apprently a bogus pointer. The change emplaces the returned optional when needed without resorting to the copy-assignment operator. So it's not suceptible to assigning to uninitialized memory, and it's more efficient as well...
