Better than letting that branch get old ;o)

It is sucky even when used with a PersistentList; it's just that the
disadvantages of its implementation are more obvious in the context of
BLists.

I'll take a look at that, thanks for the pointer.

Yes, and I think that we're talking about two steps here anyway. I'd
like to finish and release a version that uses BLists ASAP; an
additional API can always be added in a subsequent release.
