Description
Description
Fake closures are closures that reference an existing function and are most likely the result of using the First Class Callable syntax function_name(...). It not being serializable makes it harder to move from array/string callable to it.
This limited support should be easier to implement than for arbitrary closures.

Research direction
The issue names no source file, test, or entry point, so first locate the existing closure serialization handling in the PHP source and tests. Confirm the scope around fake closures created with First Class Callable syntax; done means those closures can be serialized without implying support for arbitrary closures.
