okay, thanks for the explanation, 
suggesting me to change language to rust/c is not answering my curiosity
I ask it because I'm trying to learn the runtime, and the "why" behind some 
decision that already made
for now, I will just follow it blindly, because the go developers already 
made that decision

thank you
