Oh, I was also going to point out that a simple .wrap is probably
what you want there, rather than screwing around with overrides that
depend on clobbering the class or on type changes getting propagated
to existing variables.

Of course, a .wrap could be construed as clobbering the class, but if
you don't want to change the underlying functionality, it's a lot
cleaner than replacing the method in question.
