this may be related to a thread last week about the nature lists ?
as a experienced max-user i'm having problems to understand the
nature of PD atoms. there seems to be the possibility that an atom is
neither a symbol, nor a number nor a list ? like in this patch some
inputs leave [route] through the rightmost outlet:
Check http://puredata.info/dev/PdDefinitions and http://puredata.info/dev/PdMessages and http://puredata.info/dev/HansDataTypeDefinitions
Being the author of http://puredata.info/dev/PdMessages I would just repeat myself here with text from there.
there seems to be no logic whether one has can use a message "as
such" and when one has to prepend the "symbol" selector. also there
seems to be no logic whether an object outputs a list "as such" or
with a prepended "list" selector ; like [pack] accepts a symbol
without "symbol" in the left inlet, but not in the right inlet ; it
will output a list prepended by "list" ; if i put this list into
[zl], the list-prefix is stripped.
I consider this a bug of [zl]. With newer Pd's you should use [list] instead for basic operations on lists. [list] *always* outputs a list-message with list-selector for messages with more than one element, except [list trim] which trims the selector.
also, what kind of atom is this [alpha beta gamma( if not a list?
It's something Miller calls a "meta-message". The most common example is the "set"-meta-message.
