print it out; the debug class variable allows you to do
if (debug_) printf("blah %i", metasyntacthing);

only on that variable for the particular objects you are interested in
(once you have done/scheduled $object set debug_ 1), rather than say
the other thousand or so objects your simulate-the-internet simulation
might also have running. Easier than trying to print out info to
identify which object you're looking at.

Alternatively, there's gdb and its trace and
breakpoint functionality...
