You know what's wild? The C++ community took a perfectly good .h extension and decided "nah, we need MORE options." So now we've got .hpp for "header plus plus" (get it? C++?), and then some absolute madlad invented .hxx because apparently we needed an edgier version.
Meanwhile, Winnie the Pooh here perfectly captures the escalating sophistication we pretend to feel using each one. Tuxedo Pooh with .h? Classy. Regular Pooh with .hpp? Fine, I guess. Deranged grinning Pooh with .hxx? That's the energy of someone who's been configuring CMake for 6 hours straight.
Best part? They all do the exact same thing. We just collectively agreed to make file extensions a personality trait.
