[swift-evolution] Alternative For Nested If Repetiion

[Ted F.A. van Gaalen]

.. or maybe just leave out  the switch operand like so:

     switch
    {
          case if  a > b:
                   c = 1234

          case c == d: 
                  a = b

          default:
                 doSomething()
    }

?
