doesn't
make sense for references to object x to persist in being
reference to
object x if object x has "become" object y. (The idea of
having this
in Ruby doesn't appeal to me, but that's my understanding of
its
premise, anyway.)
What evil.rb has works great for me. It should probably be
called "replace" like the methods in Array, Hash, and String.
evil.rb/become is just a more general form of the replace in
Array, Hash, and String.
