Oh threadpool, my threadpool

I don't know what I mean anymore. I tried this though:
    
    
    import taskpools,cpuinfo
    template taskPoolsAs(pool,codeBlock:untyped) =
      var pool = Taskpool.new(num_threads = countProcessors())
      codeBlock
      pool.syncAll
      pool.shutdown
    
    proc move*(hypothetical:Hypothetic,dice:openArray[int]):Move =
      taskPoolsAs tp:
        var flowMoves:seq[FlowVar[Move]]
        for pieceNr,fromSquare in hypothetical.pieces:
          if fromSquare != 0 or hypothetical.cash >= piecePrice:
            for i in dice.low..dice.high:
              flowMoves.add tp.spawn 
hypothetical.bestMove(pieceNr,fromSquare,dice[i])
        result = flowMoves.map(it => sync it).sortedByIt(it.eval)[^1]
    
    
    Run

It works, but it feels shaky:

I cannot use: for die in die:

because die becomes void - I suspect the macro

Also I receive a host of warnings and hints from the compiler, such as:
