Here is mine (and we had some chat about it internaly).

First, I am convienced that Scilab should offer some object oriented
feature.

A more overall view, IMHO, this SEP is caught between two stools ("le
cul entre deux chaises" dans notre langue).
You are taking the current Scilab language with the limitations and you
are proposing to extend the "mlist trick".
I think we must go futher in the proposal. We should not stick on the
mlist way and provide a dedicated way of doing it.

A example could be:

class myClassA:
// maybe we declare the local variable
	function setAB(variable)
		__variable=variable
	endfunction

	function res = getAB()
		res = __variable
	endfunction
	
	function res = compute(variable2)
		res = variable2 + __variable
	endfunction
endclass

// extend the class myClassA
class myNewObject(myClassA):
	function res = greatCompute(variable)
		res = variable * %pi + __variable
	endfunction
endclass

It is just a quick idea and proposal.

In the meantime, the point "have the possibility to overload macros"
should be a specific SEP which could be address in Scilab 6.
