The operation we're performing here, IIUC, is projection.  SetResult
lacks a verb, although Set could be confused with one; someone might
think this is the node that sets a result, whatever that means.
Anyway, I suggest working Project in there somehow.  If Project by
itself seems like it's too generic, perhaps ProjectSet or
ProjectSetResult would be suitable.
