> rule "PatternTest"
>        when
>                $pli:Item( title matches "^Test\s*")
>        then
>                        #
> end
> this one compiles but on Runtime it ends in an Exception when title looks for example like this "BlaBla (Test)".
> as workaround i thought about using the next part, but
> rule "PatternTest"
>        when
>                $pli:Item( eval(title.matches("^Test\s*")) )
>        then
>                        #
> end
> it resolves into, also it shouldn't (because title.matches() is Java Code a shouldn't be parsed by the DSL Parser itself):
> SyntaxfehlerRule Compilation error : [Rule name=OnlineStreaming Start,
> agendaGroup=MAIN, salience=100, no-loop=true]
> com/p7s1/swi/phoenix/n24/Rule_OnlineStreaming_Start_0.java (19:923) :
> Invalid escape sequence (valid ones are \b \t \n \f \r \" \' \\ )
