Suppose that [savestate] could take any arguments and then output them as a list when the object is loaded but its contents are empty. So for instance [savestate 1 2] would output "1 2" when it is loaded, unless it has some other contents to output. That way,
you could specify a default setting for the abstraction without having to use [loadbang], as in Miller's patch.<br>

Since you mentioned that [savestate] fires before [loadbang], I tested it and it seems that it functions as a solution for [initbang] also (great!). Ie. if you use [savestate] to dynamically create an inlet inside the abstraction, the connection will not be
broken if you save and re-open the parent patch.</div>

<div class="x_BodyFragment"><font size="2"><span style="font-size:11pt">
<div class="x_PlainText">One thing that's potentially troublesome is combining savestate and loadbang<br>
(and loadbang-like behavior built into GUIs as well.) The savestate<br>
output arrives before any loadbangs. So there's extra work to do if<br>
you want an object to initialize itself but also to use savestate. Here's<br>
an example:<br>
<br>
#N canvas 29 70 469 394 16;<br>
#X floatatom 103 123 7 0 0 1 high - -;<br>
#X obj 24 313 outlet~;<br>
#X obj 103 5 loadbang;<br>
#X obj 24 48 inlet~;<br>
#X floatatom 103 146 7 0 0 1 low - -;<br>
#X msg 103 67 1;<br>
#X obj 25 275 clip~;<br>
#X obj 375 209 f;<br>
#X obj 375 238 pack;<br>
#X obj 288 145 savestate;<br>

I badly need to update the documentation with better examples of how to use<br>
feaures like this...<br>
