Update dtor-finally.md

I'm not sure, but it looks like a typo in the function name. Now, it's a 'baz', but I think it should be 'bar'.

I think here "baz" just means "run another function". Otherwise the recursion never ends.

Hi, Marco. Thank you for your response!
In fact, as I can see, recursion ends up in a stack overflow (and the expected 'drop'=finally call won't happen and we get a good example of 'Disadvantages'). Anyway, it'll be good to have more clarifications here if 'baz' is correct. What do you think?

How can we achieve this?

[AndreiTsN]

I think, the simplest way:

fn baz( ) -> Result<( ), ( )> {
// some code
}

fn bar( ) -> Result<( ), ( )> {
...
baz( )?;
// Normal return.
Ok(( ))
}

But of course, the code can be left as it is now.
It's absolutely not critical.

this sounds like a great idea, pr welcome 🙌

[AndreiTsN]

thanks a lot! A new pr added.
