You have a bit inconsistent naming with these. The function is defined
as accepting start and end, here you use size1 and size2, below you have
foo1 and foo2.
Size is not a good name, as it's not size at all. Perhaps foo_start and
foo_end (or just start and end if there's only one feat being used)? Or
foo_msb and foo_lsb (as in most/least significant bit)?
Otherwise looks good.
