In that case, why would you knowingly tostring() a function when one of its
normal results causes an error?

I concede that much, and I have nothing further to argue. Forgive my
frustration; I've loved using Lua for several years and this is the first time
I've ever come across such an inconsistency. I was very excited to be able to
provide a quality-of-life improvement to my favorite programming language.
Thank you for your prompt and measured responses.
