no, I think this is ok. may want to unify macros with compiler side though
- stack traces - not required but may be essential
if we can record function names in cgen, then it is not too much
of a stretch to create a circular buffer of string ptr's and then
add to this buffer each time a function is called. then print the
buffer out in the default exception handler (or such).
