   @bkietz and I discussed this. Mostly it simplifies the function signature a 
lot and gets rid of the custom typechecking code in DispatchBest. It does 
require materializing scalar conditions and would need callers to do some 
pre-processing if they wish to avoid that (e.g. dropping any values associated 
with a scalar false/null condition, using values associated with a scalar true 
condition as the 'else' clause).
   
   It's mostly a point of discussion. I realized I forgot to benchmark so let 
me do that now.
