No, that's not what try-with-resources is.

This is try-with-resources:

Any object which implements the interface AutoClosable is auto-closed
in the try, regardless of an exception happening or not.

Pascal is a little different, since it has destructors, so I guess in
Pascal we could auto-free objects in a hypotetical try-with-resources
in Pascal. Something like:

try ( stringList := TStringList.Create;
 otherObj := TSomeOtherClass.Create; )
  code here
  exception block, optional

And any object in the () section would be auto-freed, auto-checking if
it was already created or not.
