Subject: Re: Inspetting a method's caller

I've always seen that whenever you need something like this, there's
always a better design choice that you can make. Like what would you
do in languages that didn't have caller etc etc.

Its still a hack, (because ideally you shouldn't be needing this IMO),
but you can make the caller send in an extra argument, putting its
description/ID/Name there.
