There are two ways of instantiating a pattern for T-Regx. Each of them accepts an undelimitered pattern as the first argument and optional flags as the second argument.
use TRegx\CleanRegex\Pattern; Pattern::of('[A-Z][a-z]+')->matches($subject);
Global function style:
Notice, that these patterns don't have to be delimitered. Smart T-Regx will conveniently add them for you. You can add flags to your regular expression by passing a second argument.

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