Hi Olaf et al,

I think that putting the indocator in the object box would cause misery,
because whenever a new name clash arose everyone would have to go edit
all their patches ... worse yet, what if two libraries are merged or for
some other reason the name of a library changes...

So, it would be better somehow to be able to specify where to find specific
classes as part of Pd's run-time environment, similarly to how "path" now
works.  This isn't a real solution either though... what if you're using
an abstraction which assumes a different "gauss" from that of the calling
patch.  I don't know what to offer for that scenario!

cheers
Miller
