That's a function of the code you've written, not whether or not its been written in Lua or XML. The global arguments are leftover from 1.x, and have been deprecated since 2.x. Also, if you use that for every single OnEvent handler, it obviously won't work since many events can pass upwards of 12 arguments. There's a reason that the WoW client sends them as variable arguments, and uses this. The conventions are all actually set by the way the WoW client passes arguments to the XML handlers, since we MUST match those names or it doesn't work. Luckily, they're sensible and well documented. See http://wowprogramming.com/docs/scripts/OnEvent.

When you see:

<Scripts>
  <OnEvent>
    foo blah bar
  </OnEvent>
</Scripts>

The bit inside the

<OnEvent>

is wrapped with

PHP Code:

function(self, event, ...) 


and

PHP Code:

end 


The moral of the story is that both XML and Lua are valid tools for writing addons, and there are things you can do in Lua that you can't do easily in XML, and there are things you can do in XML that you can't do easily in Lua.

None of that, however, is relevant for this thread which is about the deprecation and final removal of the global arguments. That's what my original response was meant to indicate.
