Are there set operations on bags beyond the DIFF operator? I'd like to
compare bags to find elements in both of them (intersection). I can imagine
union and set addition and subtraction being useful here too.
thanks

There is union as a relational operator, ie  C = A union B, but  
there's no union, intersection, etc. operators available for bags at  
the moment.  We're open to adding them.
