Any way to avoid nested case statements for proc taking two variant objects?

With `fusion/matching` 
(<https://nim-lang.github.io/fusion/src/fusion/matching.html>) you can `case` 
on tuples, so it becomes (`in <set>` to match multiple kinds, `_` for 
placeholder, and just `k1First` to match pattern directly.
    
    
    type
      Kind1 = enum
        k1First
        k1Second
        k1Third
      
      Kidn2 = enum
        k2First
        k2Second
        k2Third
    
    case (k1First, k2Second):
      of (in {k1First, k1Second}, _):
        echo "123"
    
    Run
