Today I decided to give a look at Challenge #3 since it promised nasty tricks. Now that looks like a challenge and I love challenges! If you think this is a spoiler then stop reading and come back in a week or so. There is no solution for the challenge; I’m more interested in the “nasty” trick used and why the tools are failing. And I don’t need the Challenge itself to analyse this behavior since I can reproduce it with own code.
