When you explain it that way, it makes sense, but from my perspective
as a user I have zero concern with the fact that multiple function
wrappings are happening. My goal isn't wrapping functions. It's the
right way to say "index all these types with this function". I found a
way, but it feels so wrong :-p

I experimented with making the decorator use the un-wrapped function,
when it gets called the second and subsequent times, but failed. Maybe
it could make a copy of the function? My component-fu is too weak.

If I do this, I don't see the indexer being called for the interfaces
specified by the `for="..."` attribute. Only for the
`@indexer()`-specified interface.
