i think this is partly possible (afair, maju had something like this in
desiredata).

however, i imagine it will only work for objects which are triggered via
messages (as Pd could track when a message enters an instance, and set a
static variable to this instance)

otoh, it most likely won't work with objects triggered directly by
t_clock events, it makes delegation hard (e.g. when creating an
abstraction, you might want to appear a message to come from the
abstraction itself, rather than from one of the objects inside of the
abstraction...cf. iemgut's "pderror" object)
and it will go havoc with multithreading  (not that Pd properly supports
multithreading; however, i'm a firm believer that global states are evil
and we should try to generate as few "thread-unsafe-by-design" code)

finally, "post()" is sometimes used to printout messages that are not
associated with an object at all.
e.g., where do you want to jump to at "I/O error, audio stuck", or at
"GEM: Authors :	Mark Danks (original version)"


therefore i think it is a good idea to make the new logpost() behave
similar to pd_error(), as it allows us to explicitely associate an
object (of our choice!) with a message.
since it might be a nice feature to have traditional "error" and "post"
messages associated with an object, this functionality could be added
for the sake of those old APIs

but let's not do automagic if there is no need at all.
