    \$\begingroup\$ @RGS Yeah, could have just gone with the 9-byter, haha. I golfed it while adding the explanation (thus before posting) and realizing it could be shorter. EDIT: I've removed the strike-through 10. \$\endgroup\$ Commented Feb 24, 2020 at 14:46
  • \$\begingroup\$ If I golf my answer within the grace period then I never strike through because there's no way to recover the previous version. \$\endgroup\$ Commented Feb 26, 2020 at 10:25
