Fidgets!

I'm trying out a new syntax using rather. What do y'all think?
    
    
    Vertical:
      itemSpacing 1.5'em
      
      Vertical:
        itemSpacing 1.5'em
        
        # Trigger an animation on animatedProgress below
        Button:
          label = fmt"Arg Incr {self.count1:4d}"
          proc onClick() =
            self.count1.inc()
            delta = 0.02
        
        Horizontal:
          itemSpacing 4'em
          
          Button(label = &"Evt Incr {self.count2:4d}"):
            onClick = block:
              # blocks also work
              self.count2.inc()
              currEvents["pbc1"] = IncrementBar(increment = 0.02)
          
          Theme(warningPalette()):
            Checkbox(label = fmt"Click {self.myCheck}"):
              checked = self.myCheck
    
    
    Run

vs the current syntax:
    
    
    itemSpacing 1.5'em
      
      Vertical:
        itemSpacing 1.5'em
        
        # Trigger an animation on animatedProgress below
        Button:
          label: fmt"Arg Incr {self.count1:4d}"
          onClick:
            self.count1.inc()
            delta = 0.02
        
        Horizontal:
          itemSpacing 4'em
          Button(label = &"Evt Incr {self.count2:4d}"):
            onClick:
              self.count2.inc()
              currEvents["pbc1"] = IncrementBar(increment = 0.02)
          
          Theme(warningPalette()):
            Checkbox(label = fmt"Click {self.myCheck}"):
              checked: self.myCheck
    
    
    Run
