get instance variable name from itself in ruby

Question

I have an instance variable @foo and I want to write some code so that I get string \'foo\'

any hint?

Answer 1

In Ruby, you can only manipulate objects. Variables (including instance variables) aren't objects.

Besides, what do you want your magic method to return in this case:

foo = Object.new
bar = foo
@baz = bar
@qux = bar

magic_method(foo) # what should the return value be and how would it know?
