What you appear to be asking for, is the name of the local variable
(bobo) that holds the reference to the object on which the method is
being called. I do not think this is possible, since it could be that
there wasn't a local variable holding a reference when you called it
(such as if you called A.new.myname).

Even with the name of a local variable in the outside scope, you'll need
a binding to that scope to access it. A little more code showing what
you want to do with the name of the local variable would probably spawn
more concrete, useful answers than this one.
