There are a few Cops and Robbers posts on Code Golf SE, where there are two posts - one is the "cops" post where people post problems of a very specific type, and the other being the "robbers" post where people answer these problems. Points are earned by both cops and robbers for the difficulty of the posts they create/solve
I was thinking of making a Cops and Robbers post of this question. Basically, users will try to create construction problems that can be solved with a straightedge and compass, but not just with a compass. Others would try to achieve these tasks using just a compass.
I'm not sure how to score the answers, or even to score them at all. Could you please let me know whether this puzzle would work, and what changes could be made in it?
P.S. I normally don't sandbox questions on Meta SE like this, but I'm making an exception because this might just evolve into a whole new category of challenges.
