Lua debug.traceback() Function: Call Stack Traceback

The "debug.traceback()" function returns a string with a traceback of the Lua call stack. It starts with a message describing the traceback and then lists all active function calls in the stack.

Here is an example usage of the "debug.traceback()" function:

function foo()
   bar()
end

function bar()
   print(debug.traceback())
end

foo()

In this example, the "foo()" function calls the "bar()" function, which then prints the traceback using "debug.traceback()". The traceback shows the call stack, indicating that the call to "bar()" originated from the call to "foo().
