No, Ada access types are just pointers -- no "smarts".
To make something like smart pointers, you can use
controlled types.

Dereference of access types uses the syntax ".all", but it's allowed to
be implicit in most contexts (for example, X.Y means X.all.Y, if X
is an access value (pointer)).

No.
