Smalltalk super keyword implementation in Amber

I was experimenting a bit and wondered into Amber's Javascript land. Calling 'self something' executes the method on anObject if it doesn't find it there method lookup goes up the inheritance chain to the superclass and the super of the superclass.

Where does this super happen in Amber?
Could one mess with it?

Try to compile a super call and look what JS it produces and learn the rest from it.

Or did I again not understood what the question is about?

Re: Smalltalk super keyword implementation in Amber

You got it!

Your advice sheds some light on the problem:

//>>excludeStart("ctx", pragmas.excludeDebugContexts);

$ctx1.supercall = true,

//>>excludeEnd("ctx");

$globals.WhateverClass.superclass.fn.prototype._initialize.apply($recv(self), []));

//>>excludeStart("ctx", pragmas.excludeDebugContexts);

$ctx1.supercall = false;

//>>excludeEnd("ctx");;

I'll dig deeper.
