typehint validator win if if all the elements are valid. However, it will very slow when the array has an invalid elements. When typehint throw a TypeError exception, it will generate a huge back-trace. When the number of elements too many, PHP will waste memory.
In addition, this benchmark indicates that the show is a high throughput more obvious if statement in the loop than call the callable object. (Since the future of PHP may show different performance, you should not be blind faith this result.)
