I don't know if this was designed this way purposefully, but it makes
sense to me. I see nothing out of the ordinary here. It makes for some
really nasty code, but that can probably be said about all code that
uses references.
If we try to simplify your example, we can see more clearly what's
I want to ask about a quirk that I happened upon. In truth, I expected my
code to fail with a fatal error, but it turns out that while using array
destructuring in the head of a foreach() loop it is permitted to declare
new elements if the value is a reference.
Is this a bug or an intended
