I'm fine using someone else's merging routines. And I admit to being a
bit afraid of creating an ugly syntax here.

I was originally concerned about backwards compat, as some people probably
rely on a subsequent overriding a previous one. But if we do change
behavior, we might be able to make it a config option that could be set and
immediately applied, so that subsequent parts would use it.
