That's just the writeln array formatter. The matchFirst function 
returns an array of hits (that allows captures, btw you might 
need to use \( instead of ( to get the capture, god i hate regex) 
so writeln tries to print the whole array and that's how it does 
embedded newlines.

So you have the correct result, just written strangely.
