Thanks; I should have checked the bug list.  Can I contribute a unit
test?  I would think something like:

  test(88.5, TESTDT[a=="d",list(MySum=sum(v)),by=list(b)],
    data.table(b=INT(6,9), MySum=INT(7,11)))

would work.  (That's based on just a few minutes of looking at the
sources, so I may have mangled something.)

Thanks,
Johann
