[Swift-devel] swift compilation error on compound expressions

[Michael Wilde]

This script:

--

   string st = "foo";
   string tu = "bar";
   if  ((st != "") || (tu != ""))  {
     if ((st != "") && (tu != "")) {
       trace("sweep");
     }
     else {
       trace("Error");
     }
   }
   else {
     trace("simple_loop");
   }
sur$


gives:

--
