R help - May 2007 - geeting name of an object to which a variable refers?

#Sorry for the convoluted subject line.

#I have:

a=c(1,2,3)
x=a #example of user supplied input


#Is there any function that will tell me the "name" of the object x
refers to, referring only to x itself?
#i.e. the "answer" I want is "a"

#I want: 
#fun(x) == 'a'

#(I don't think this is possible, but figured I'd ask.)

Something like this?

R> f <- function(x) deparse(substitute(x))
R> a <- 1:3
R> f(a)
[1] "a"
