> Concatenating/slicing selectors tricker
It seems just adding "0" on odd elements to denote "select 0" gives the same
meaning?
Currently the output of
> Can not accept row selectors that have two consecutive select/skip.
Skip (5), Skip(5) is identical to Skip(10), so what would be the benefit
from having consecutive select/skip?
> Another potential option might be an enum like this:

Downside is that it is also 16 bytes per element instead of 8.
