Muito bem ruoso.
A very nicely crafted analysis! Abrigado...
But you know, I readily admit that in all of my submissions "there is no much complicated obfuscation".
So I eagerly await your own obfuscation. I think you will be very good at them!
(I don't promise to be able to analyze it as well as you did mine, though -- I still have a lot to learn from the obfuscated code examples).
