new example:
   for (<init>; <cond-a>; <incr>) {
       if (<cond-b>) {
          try { // is C++, but doesn't matter
             <code-a>
             if (<cond-c>) continue;
             <code-b>
          } catch(...) {
             <code-c>
          }
          <code-d>
       } else {
          <code-e>
       }
   }
Python: ?
  With some effort, one can surely craft equivalent code in Python,
  but I bet it will become considerably longer, and likely you'll 
  have to repeat some of the code-blocks, or introduce new flag-variables.
point taken ?

Yes, it occurred to me already:
   case=lambda x: my_special_compare(switchvar,x)
   if case('blah'): ...
   elif case(42): ...
   elif case("foo") or case("bar"):
     print "sufficiently near to a fallthrough :-)"
   elif case(r"^(.*)foo(.*?)$"): ...
   ...

switch is indeed not needed in python.
