Hmm, if there is a symbol with the same namespace in the generated file and the special file, when I build it is crashing, so I either have to remove all the atomic symbols from the special, or instead of changing `std::` to `None` in the code I should exclude the `*.h` headers for symbols with not None namespace, and add them back in the special file. 
What do you think?
