As has been pointed out to you, the whole point here is that string
objects often *are not* distinct, despite conceptually having distinct
cretion in the source.

That's why an ‘object()’ invocation is recommended: because it *will*
create distinct objects. Strings do not have that property. So strings
are *not* suitable for this use case.
