Thanks for the tip.  Besides that, are there any other gotchas related
to redefining methods?  For instance, I'm redefining my_foo inside
module x, but y and z call my_foo before module x ever needs to get
loaded.  Does that mean that my_foo will be the old version for y and
z, then the new version for any callers after module x gets loaded?
