[PD] creation arg, distinction between 0 and no arg, WAS Re: Splitting Objects

[Jonathan Wilkes]

If you use Pd-l2ork there is no need for dirty hacks.

Using...

[list append $@]

... you can get all the arguments to the abstraction.

Obviously once you have them you can check to see
whether the argument exists, and if it does not set a
default value.

If you use iemguts or my patch on the tracker that gives
you parent args all the way up to the toplevel you can
encapsulate the process of setting default arg values in
an abstraction.
