You assume correctly! If you are prepared to help out (if you are, obviously I'd be very pleased to give lots and lots of help). I think the way forward would be for me to add (and use, to shake out bugs) the type implementation, then these algorithms would be in a separate PDL::BitOps or similar distro.

My immediate "itch" was to use a bitmap to implement seenmap in the fancy new contour_polylines; it annoyed me a bit that while I'd made that be a byte (i.e. 8-bit) ndarray, I was only using 2 of the bits in each of those. It's not a vast amount of memory being wasted, but that has an impact on cache usage.
