Aren't optional parameters and allowing NULL for typehints two different
pairs of shoes?
At least passing NO parameters and NULL as parameter is easily
distinguishable in userland:
$ php -r 'function test() { var_dump(func_num_args()); } test();'
int(0)
$ php -r 'function test() { var_dump(func_num_args()); } test(NULL);'
int(1)
