Class method style:
Global function style:
Notice, that these patterns don't have to be delimited. Smart T-Regx will conveniently add them for you. You can add flags to your regular expression by passing a second argument.```php pattern('[A-Z]+', 'im')->test($subject);

Of course, you can still use delimited patterns with flags. Both versions are equal with each other.
