Hi,

I don't know the answer but I think should be exactly the same.
Even if not, I strongly recommend you to use interfaces instead
"try-finally" approach
because you gain more than just automatic memory release.

PS. I have a blog about Object Pascal. I write about real
object-oriented approach.
The blog is written in Portuguese but using Google Translate I guess
you won't have
problems to translate.
