Yes. Either lua_tostring() will change the key into something else,

I have to say that the automatic coercion between strings and numbers
in the
Lua API is one of my least favorite features. I had mostly seen it as
unnecessary cruft in the past. This thread points out that it is
downright
dangerous.
Could we perhaps see a shift in which the core API did not do the
conversion, but luaL_tostring and luaL_tonumber would do so?
Furthermore, it
would be nice if luaL_tostring was essentially the same as invoking
tostring
on the value so that it could handle arbitrary objects.
