overload init function in class/object ? [message #34990]

I was under the assumption that you could overload the
init function of an object.

However, it doesn't work for me.

In the below example I get an error if I try:
IDL>o = obj_new('obj')

Yet this works:
IDL>o = obj_new('obj','test')

I wanna be able to overload my init functions!
Please tell me I'm doing something wrong.

;--- obj__define.pro -------------------

function obj::init
compile_opt idl2
return, 1
end
;-----------------------
function obj::init, p1
compile_opt idl2
print, p1
return, 1
end

;-----------------------

pro obj::cleanup
compile_opt idl2
end

;=======================
pro obj__define
compile_opt idl2

obj = { obj, $
d1: 0, $
d2: 0 }

end
;=======================
;--- obj__define.pro -------------------
