It is easy to create a map from a list of object, using #PHP array_column() and the second argument null.
That null represents the whole object, and the third argument is the indexing key.
array_column($list_of_objects, null, 'id');

It is not possible to cast any #PHP enum cases to (string) or (int) even when... they are backed!
That looks like a natural feature, though.

It also applies to enumeration cases.

There are, at least, 4 ways to create a closure in #PHP. They all will be callable later.
On the other hand, they behave differently to check the underlying method.
All is in the timing.

A few days ago, I warned about isset() and a possible #PHP Fatal error.
Given that isset() and ?? share the same code, it is not suprising that ?? hold the same trap.
That bug should go away, the sooner the beter.

When using #PHP isset(), the language construct hides errors because, that's what is being tested there.
Unless there is an object, where an array is expected. Then, it leads to a fatal error.
It prevents the usage of an optimisation.

But not on both at the same time.
