Rename unused for loop variable _ instead of i

[paruby]

I was trying to understand the code and found it a little confusing because the i wasn't used in that for loop, but there was another below where it was used.

(I'm a googler, let me know if it is better to make a commit internally instead of publicly)

Hmm i signed the CLA but the check is still failing. Maybe it needs some time to propagate or it needs to somehow be re-triggered manually but i'm not sure how to do that

Thanks @paruby

Ah it was my bad about the CLA thing, I had not clicked through the link to refresh the check

I don't see a button to submit the PR, does that have to be triggered on your side @MayankChaturvedi ?
