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).
