An earlier version of my Pitfalls of VLA in C article contained an example of useful case of VLA, which I pulled out of it as I decided the two – although I'd be overjoyed being presented with more – cases where VLA are clearly useful, deserve their dedicated, if low effort, post. After all, those use-cases are the only reason why I compile with -Wvla-larger-than=0 rather than more strict and reliable -Wvla.
