Bah, I forgot to assign that function to anything, AND I'd need to save/restore those variables for stack-based calls/exits.

Closer to:

function AKClass.prototype:addMethod( inName, inFunc )

local theClass = self.class

self[ inName ] = function( ... )

local oldSuper, _super = _super, theClass.superClass

local oldMethodName, _methodName = _methodName, inName

local theReturnValue = inFunc( unpack( arg ) )

_super, _methodName = oldSuper, oldmethodName

return theReturnValue

end

return self[ inName ]

end

Definitely not something I'd consider implementing if either speed or memory were tight, but a fun mental exercise in pure hackery, nonetheless.
