What is the easiest way to return a variable or object name from a method in Ruby?

Say I set some variable to a value as such....

some_var = 1

And I want to define a method to return the variable name rather than the value. Like so 

def return_method ( argument )
    puts  "some_var"  #comment ----- if some_var = argument
end

How can I elegantly do this?

Your function is going to return the value of a variable not the name of the variable.

If you want to return the name you could puts a string. So for your example you could run a for loop like: if some_var = argument puts "some_var"

If you didn't want to print you could also use return and return the string.
