If it was a week or two ago, the quiz was probably from the same person as this article. He's not just doing it for fun; he's a professor at the University of Utah, and he's researching this area, looking for bugs in compilers.

Nobody's doing ++x > y, but they do something that looks reasonable like foo(x) > bar(x), where foo() and bar() return chars.
