And also to developers: Some of the annoyances with list- vs.
"meta"-messages are introduced by externals like those inherited from
Max: [prepend] in all or most of its versions except [list prepend] or
the zl-family or - in a different way - [OSCroute], because these
output a meta-message even when they receive a proper list-message and
thus may introduce unwanted side effects later in the processing chain
if users aren't aware of this. 

AFAIR Miller's objects all work in something one could call the
"list-message domain", which successfully prohibits these side effects
from occuring, which makes list-processing a very comfortable thing
again. If needed, translating a list-message to a meta-message is
trivial, and generally this translation only is needed directly in
front of an object when a meta-message is needed to access a method of
this object.
