Instances do not have names; what you have above is a variable (named 
'fun') that references your instance. For example, consider this:

my_array = [ Someclass.new ]
wow = my_array[ 0 ]
my_hash = { :foo=>my_array[0] }

wow.say_hi
my_array[ 0 ].say_hi
hy_hash[ :foo ].say_hi

What would you expect that method to output?
