There are two ways of instantiating a pattern for T-Regx. Each of them accepts an undelimited pattern as the first argument and optional flags as the second argument.
Class method style:
Global function style:
Notice, that these patterns don't need 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.

Of course, you can still use delimited patterns with flags, with
Pattern::pcre(). Both versions are equal with each other.
