BitSets crop up in (at least) C++ and Java. They allow you operate on
a sequence of bits using a friendlier interface than hacking about
with ^,|,& et al on integers. The Java BitSet interface:

I can't find anything like it in the standard library (If I've
overlooked it, I'd be chuffed to find out I'm wrong!). The OP might
find the following Cookbook recipe useful, though:

(At least I think so, I can't access the site at the moment...)
