afaik, you'd need [initbang], but that object class has not yet been
introduced in the main pd, so the best you could do is decide of a maximum
number of inlets or outlets, create that many, and use [loadbang] to
delete any extraneous inlets or outlets. If you try to create inlets using
[loadbang], they will be created too late when you reload the patch, such
that every patch that has connections to such objects will load with
"connection failed" errors that result in missing wires.
