It's trivially changed to
try { code_which_can_throw(); only_if_didnt_throw(); }
catch { handler(); }
finally { mandatory(); }
So, even assuming that scope statements aren't the best fit (e.g. because
you actually need access to the exception, or you don't want it to be
rethrown from the catch block), the default block is pretty pointless as far
as I can tell.
