The first thing that popped into my mind when I read the question was a data-processing script I wrote at work in three days that saved hundreds and hundreds of person-hours of manual work, a task that had stumped a couple of better programmers than myself.

If Nicolas Bize would accept that sort of thing, I think it's a good test. If not, yeah, it's problematic.

Edit: I've just asked him about it in comments under the original post.
