The simple answer is: it doesn't need any :) since Lua will just fill 
in the missing ones with nil.

A better question would be "how can i determine the maximum number of 
arguments this function will care about?". But I don't believe there is 
a way of doing that.

If you really want to associate functions with introspection 
information, I think you'd have to create some mechanism to do it, like 
a weak-keyed table of functions whose values are the function 
signature.
