Just to be clear, I suppose you (both) are talking about
"member references"? EG: Nested classes?
I found calling member class references as nested classes
confusing - they are very different.
Destroying an object 100% guarantees its member destroyers are
also called, outer to inner, first in first out, as part of the
destruction process. The thing is that when you store a "class
reference" then you call the destructor of the reference
itself. References being glorified pointers, it basically means
it does nothing.
Are you implying that in following code snippet:
class A { ~this() { ... } }
class B { A a; ~this() { ... } }
destructor of A will be always called after B, so "a" member is
always accessible in B's dtor?
