Immutable variables are not lvalues, you can't take address of them because
they might not present in a final executable. For example, everywhere you use
val, it is replaced with 23. You can't return 23 by reference, can you?

Besides, returning immutable values by mutable reference is disallowed:

func() = 42; //what should this do if func() returns reference to immutable
val?
