Yes. Good idea. We can follow Data.Map/Set on this.

Like I say, this has come straight out of darcs, and wasn't being
developed as an fptools-style library, so it needs some polishing.
However, enough interest was shown when it got used in h4sh, that I
figured it best to cabalise and release as is -- which is definitely
fast if not always pretty :)
