Given a string like "Rich36!", it would produce \w{4}\d{2}\! or \w+\d+\!.

And why wouldn't it produce one of these 

    /\w{6}!/
    /\w+!/
    /[A-Z][a-z]{3}\d\d!/
    /Rich36!/
    /......./
    /\S+/
    /.*/

I mean, the tightest or least general thing it could produce when given a $string is just /\Q$string\E/ and the most general thing would be /.*/s, and between those is a rather large space of candidates.
