I think you said the word: serialization. And especially*deserialization*,

Would is_initialized() actually be all that useful there though?
- If you're iterating the properties dynamically, you'll probably be
using the reflection API already
- If you're listing them manually, you can validate the input rather
than the output, which you'd have to do if there's any mapping of names
or types anyway
It's also worth noting that If the property is not nullable, you can use
isset() to tell if it's been initialised; and if it is nullable, you
probably want it to default to null anyway.
A separate function is only needed if you've decided to use the
uninitialised state as an extra "value", distinct from null.
