Have done it, never enough of an audience to be totally humiliated. It's never going to be more efficient.

But as for your cringe issue that the audience noticed, one could see that to be a benefit -- prefer to have someone say e.g. "you typed `Normalise` (with an 's') again, C++ is written in U.S. English, don't you know / learn to spell, you slime" upfront than waiting for compiler to tell you that `Normalise` doesn't exist, maybe?
