>Is there a method in Lua to check from within a script if the function is

To check whether f(x,y,z,...) is ok, just do
	if type(f)=="function" then f(x,y,z,...) else do-something-else end

However, this will not work if f is an object for which there is a "function"
tag method.

This should work in all cases.

What exactly are you trying to do?
