That sounds crazy but if it's really what you want, you can probably
fake it by examining the control stack using the backtrace module.  I
remember doing some hack of raising and catching an exception in order
to retrieve the backtrace, but there might be a cleaner way that I
didn't bother researching since it was just for a quick debugging
problem.
