the secrect is [initbang], which fires when the abstraction is ready 
(rather than [loadbang], which fires when all the patch (with all the 
abstractions, sub-patches and what not) is ready)).

unfortunately, i haven't found a way to make [initbang] without hacking 
Pd itself, so it's not part of any library (e.g. iemlib).

instead, there is a (low-level) "patch" for Pd somewhere in the tracker, 
which is applied to Pd-extended (but unfortunately not to Pd-vanilla).

thus: if you want to need [initbang] (which you do if you really need 
variable in/outlets in abstractions), you need to either compile Pd 
yourself or use Pd-extended (only the core binary, no need for any 
externals here)
