Replace isValid() calls with assert()

There's more value on showing how `assert()` displays the validation
messages than simply showing if `isValid()` returns `true` or `false`.

However, that increases the chances of having outdated documentation, so
I created a doc linter that updates the Markdown files with the
correct message.

IterableVal

IterableVal()

Validates whether the input is an iterable value, in other words, if you can iterate over it with the foreach language construct.

v::iterableVal()->assert([]);
// Validation passes successfully

v::iterableVal()->assert(new ArrayObject());
// Validation passes successfully

v::iterableVal()->assert(new stdClass());
// Validation passes successfully

v::iterableVal()->assert('string');
// → "string" must be an iterable value

Note

This validator doesn't behave as PHP's is_iterable() function because it considers that you can iterate over any object.
