Hmm, this is rather nice. I can imagine possible use cases for switch x: case > 3: foo(x) case is y: spam(x) case == z: eggs(x) An interesting use case for which this offers no corresponding syntax is case instanceof ClassA: ham(x)

Actually, I was assuming that any other operator besides == and 'in' would be relegated to an if-elif chain in the default case, although it's almost possible to do that automatically, I suppose.
