Thanks a lot.

As per the manual that is contained in the repo of Lua(
https://github.com/lua/lua/blob/master/manual/manual.of),
which says that [emphasis mine]:
Whenever Lua calls C, it ensures that the stack has space for
at least LUA_MINSTACK extra **slots**.
             ^^^^^^^^^^^^^^^^^^^^^^^^^^
LUA_MINSTACK is defined as 20, so that usually you do not
have to worry about stack space unless your code has loops
pushing elements onto the stack.

The same question arises, what does the "slots" mean for Lua?

Thank you for your attention to this matter.
Best Regards
