I think you got something wrong in your demonstration. That code is
not calling "tellme", which could still be nil (or any other
non-callable value). It's calling the function that was already on the
top of the stack before you called lua_getglobal. And the function
will receive exactly one argument, the value of the global "tellme"
variable.
