❔ Can someone help me fully understand ref returns?
I have not been able to get this through my head aside from a few things like never using a ref return if a variable does not exist outside of scope. What about something like keeping local variables alive through ref returns?
Seeing the Span<T> type do these things confuses me. How is it able to do something like this considering ref return constraints, knowing it's a ref struct only on the stack? It's local but the GC knows it's still in use after returning
But you can't do anything like this which is what confuses me about the whole thing:
