There's a PEP for sets that looks pretty good to me.  They look
more useful than bools.  They actually make some tasks easier.  
I haven't heard yet how bools make anything easier.

quaternions can be implemented by a module like cmath, if useful.
Alternatively they can be represented as 3x3 matrices in Numeric.
