When inside an abstraction, let says foo/bar.pd, if you want to use an
external that is named [bar], Pd complains :
"error: bar: can't load abstraction within itself
 bar
... couldn't create"

And then, let say there is a "foo/counter.pd" in the same directory
and that you wan to create a [counter], it will instanciate the
"counter.pd" that is in that folder, and not the external that is in
/usr/lib/pd/extra, for instance.

So yes, such a design is neither problems-free, nor a panacea, but so
far our abstractions development has been overall facilitated a lot by
the use of categories like these, and the Subversion repository that
goto10.org is providing us.

Now, we'll  change a few more things, and make it (finally) part of
pd-extended. Don't hesitate to suggest a better suffix than "_" for
the abstractions that provide a Graph-on-parent GUI, as we would like
to change for a better one, if one exists. (maybe "$". "|", or "+",
such as in "rgb$" or "rgb+" ?) Also, feel free to suggest some of your
abstractions to be part of this.

By the way (regarding $args and $), I wrote a [flow/pak] that is a
[pack] with all inlets hot ! (using dynamic patching)
