+1

$int     instanceof Int
$float  instanceof Float
$num  instanceof Numeric
$bool  instanceof Boolean
$str     instanceof String
$array instanceof Array

This makes it possible not to use the is_*() functions.
It is desirable to conduct instanceof fully consistent with behavior
hinting casts, it would be logical and correct.
Just wanted to be able to use these classes (or interfaces) to create
their objects, these objects would pass inspection in hinting casts.
