example for "boolean or object" is 'date_create' [1]. Afaik there is no built-in
function, that returns a closure, so
the combination "boolean or closure" is not possible at all.
Hm... date_create is an alias of DateTime::__construct and as far as I understood __construct
returns usually an object
and false only in the case where an exception has been thrown anyway. Right?
