It's going to be so very marginally slower that you won't even be able
to measure it, outside of a micro-benchmark. Worry about code
correctness first, and then performance only if you actually know you
have a problem.

Sharing state between modules is fine as long as it's controlled by
one module - which is what you have here. Go ahead! Not an issue.
