Iterable

• v::iterable()

Validates if the input is iterable, in other words, if you're able to iterate over it with foreach language construct.

v::iterable()->validate([]); // true
v::iterable()->validate(new ArrayObject()); // true
v::iterable()->validate(new stdClass()); // true
v::iterable()->validate('string'); // false
