Thank you Raul! I thought I was agreeing, until I got to the following: > On Oct 14, 2019, at 11:40 AM, Raul Miller <[email protected]> wrote: > > So ... it's the "only the nub" which is relevant here, if you do not > care about the calculation which produces the result.
What calculation? What would be different if (I was allowed to) just supply (~.x) as a left argument? (Assuming I didn't care to waste the cycles calculating the nub when it, at least its size, is going fall out as a result of looking up each of the eight argument rows). But I'll accept that I'm missing something; the alternate that Roger suggested looks like it should do exactly what I was looking for.
