Hello,
Let us say we have a hash:
a = Hash.new
Can I do something of this sort:
class Hash
def who_am_i?
"#{self.symbol}"
end
end
Where self.symbol gives me "a"?
I basically want the variable name. I looked a bit and saw that you
could intern a symbol from a string, but is there an easy way to get
the name of a variable from within the object itself? I am writing a
to_xml method for hashes and it would be immensely helpful if I can
use the name of the variable as the root element.
Thank you,
Jayanth

The hash has no knowledge of how many identifiers refer to it.
Consider this:
a = Hash.new
b = a
c = b
The three identifiers are in exactly the same relation to the hash.
What is the hash supposed to think?

I totally agree with David but will take his idea a bit further:
What you're asking has what we call a "bad design smell"... I have never seen a legitimate need for what you're asking for all the good reasons that David mentioned. You need to look at the design of your code and ask what you're really trying to accomplish. Something is currently wrong with the design you're currently attempting.
