I honestly don't see what this adds over if statements. You save typing `match ==`? I guess indent block is visually more clear than series of ifs/elifs? That's kinda already solved with pep8 styling of separating logic blocks with newlines.

  match response.json()["status"]:    
       case "500":      
          raise DeadServer()     
       case "404":    
            raise BanServer()

  vs
  
  status = response.json()["status"]    
  if status == "500":       
      raise DeadServer()    
  elif status == "404":       
      raise BanServer()   

there's some clarity here but at the same time it's an extra indent layer, soon we'll have:

  class Client:
      def download(url):
          with open_connection() as session:
              while True:
                  response = session.get(url)
                  match response.json()["status"]:
                     case "500":
                         raise BadServer()
                     case "200":
                         return response.json()

As much as I love python's indentation this is getting a bit out of hand, isn't it? Did we run out of things to add to python?
