There is a similar-ish thing in Poland but I don't know how widely it's used or the details of it. You can formally ask to be punished right away. The prosecution must agree too and the court must find that what you said proves that you did what you claim you did. The upside is that it's quicker for you and you can try to get your punishment to be lower, the upside for the court and the police is that they don't have to do a lengthy procedure as they would if you tried to fight back. You also can't do it for crimes that are a "zbrodnia" ('fedolny, sort of, minimum 3 years in prison), just for ones that are defined as a "występek" ('offense', .. again, sort of).
