This code allows to replace calls like:
```php
if (in_array($request->getMethod(), array('POST', 'PUT', 'PATCH'))) {
    // do something
}
```
With:
```php
if ($request->isMethod(array('POST', 'PUT', 'PATCH'))) {
    // do something
}
Well, what if $method is an object? :)
My solution is not production-ready, there must be some checks
