The .bss section is simply a way of saying 'I want this amount of space beforehand'
You cannot store extra information in the section, it's entire purpose is preallocating space, and it does not allow initializing the data beforehand.
Should the size of the .bss section count against the score?
This is aimed at x86 Assembly answers, and probably isn't applicable towards C/C++/Jelly/Brainfuck and others.
