[Python-Dev] PEP 275: "Switching on Multiple Values", Rev 1.1

[Jack Jansen]

Even though I'm not sure I like the switch idea (and I won't even contemplate 
how Guido will react when he comes back and sees what we've been spending our 
time on:-) there's one very special case of switch that I would like, and 
that's the Algol 68 style switch on type. If we had something like
  def foo(x):
     switch type(x):
        case int:
          do something
        case string:
          do something else
this would be a nice point to hook into for something that tries to compile 
Python to C or somesuch.

Hmm, you would probably need a tuple-based switch as well:
   switch type(x), type(y):
     case int, int:
        ....
