Nitpicking Memes

The classic code review saga continues! The function claims to check if something is a valid number, but instead uses a regex that would make ancient monks weep. Meanwhile, the reviewer's profound feedback? "add period" to the comment. Because clearly, proper punctuation is what's going to save this regex abomination from summoning demons in production. Seven years of computer science education and a decade of experience just to argue about periods in comments while that regex sits there like a ticking time bomb. Priorities!
