You can use set_trace_function to record this kind of information at
runtime.

I can figure out who sent a message to an object. Couldn't figure this one
out from the ref manual or the "Programming Ruby (&c)" book. I know
Kernel::caller exists, but it only returns the calling method and line
number in the source, nothing about which object/class the method is
associated to. Being the whiny bastage I am, I'm not satisfied with this,
and I want to find out all sorts of trivial information about the caller of
my methods. I don't let my methods hang out with delinquent classes :)

Could be just #caller for example
