Your proposal suffers from same issue. Although idea of unique
can be worthy, without escape analysis it is another hole.
Wow... that looks really unsettling.
But as far as I can tell, you are declaring an immutable
pointer, and the pointer itself never changes. After all, this
looks correct. Or am I missing something from the language
specifics?
Actually it is fully immutable, which means that both pointer and
pointee are fixed. This is not the case and that's why it is a
hole.
