[PD] Get list of a the arguments of a patch without using any external?

[Jonathan Wilkes]

Right.  We discussed before somewhere on the list but I 
couldn't figure out where.  Here's the same solution but only using a 
subpatch.  Just use "testab.pd" as an abstraction, give it some args, 
and bang [pd get-my-args] to get your args.

(Then just copy/paste [pd get-my-args] into any abstraction where you 
want to get the args.)
