Your problem is right there: 'super' cannot be a straight attribute

your object context instead.
I see! You're declaring a local variable 'super' in order for it to
be captured in the closure of the init method. Tricky.
Which yet again points to the fact that 'super' type methods can't be
written using first-class functions in a way that allows them to be
used and re-shared. Pity.
Hrm...unless I went crazy-stupid and used global variables and
wrapper functions. Something like...
function AKClass.prototype:addMethod( inName, inFunc )
local theClass = self.class
return function( ... )
_super = theClass.superclass
_methodName = inName
return inFunc( unpack( arg ) )
function AKObject.prototype:super( ... )
local theSuperMethod = _super[ _methodName ]
if theSuperMethod then
return theSuperMethod( unpack( arg ) )
Thanks for the discussion.
