Agreed, I mentioned that in the F43 direct dangling reduction attachment.
There is no scenario in which that is ever good. It is always bad.
Making the compiler more complex to report that as an error doesn't make
the language more complex. We would just be making the compiler take more
responsibility for the stack which it is already responsible for.
The compiler doesn't even have to look outside the function to see that it
is wrong, since it is a direct local instead of an indirect one.
