I think the distinction being made is maybe that in (say) Java trying to print on a closed filehandle object would throw an IOException which your code would be required to handle, whereas perl  -E 'close(STDOUT);say qq{FOOP}' will run (producing no output but also not printing any sort of error (although you could check the return from say and print $!)).
