Now I got it, thanks. Far as I can tell in this case it doesn't make a 
big difference, is that correct?

a) with try/catch: Exceptions are transformed in AssertError, Errors 
just go through

b) with scope(failure): everything is transformed in AssertError.

There is a difference, but both behaviors would be acceptable.
