... and it will further become LookupByNode shortly, but that will be

It's possible these could be dedup'd... a lot, honestly.  I'm wondering
if they actually need a discrete type per kind at all, anymore; it's
seeming much more tractable to try to turn that into a "no" after all
the other successful work this morning abstracting things.

But I have some other things I want to ship and do demos and prototypes
of that's a lot more interesting than shaving more lines off today.
So just gonna roll with the existing convention and stamp these out.
Might deserve a revisit in the future.  Might not.  Time will tell.
