Variable Scope in ActionScrip 3

Do you know what happens in the follow code?

Compile error? Runtime Error? Nothing. The trace result is “Name: Bruno Sales”. The variable was created even if the code inside the IF was never executed.
Thats happens because ActionScript has just 2 types of scope: Global and Local; remembering that Local is everything inside a function.

However, I suggest never using something like this in your development process. Your code logic will be very confusing and will cause problem to maintenance and debug.
