Not really... not in this case, anyway.  :)

Consider this code:

a = someObject
b = someObject

# insert magic code here to
# change the class of someObj
# by manipulating 'a'...

puts b.class

# If we successfully changed
# someObj, then referencing
# 'b' should reflect this.


If you can write the "magic code"
that manipulates 'a' but not 'b'
and then show that 'b' has changed,
I would believe you had accomplished
a 'become' operation...
