And my indentation and brace-balancing there is wrong. Shows how 
dependent I've become on syntax highlighting.

     import core.time;
     import std.concurrency;

     bool received = receiveTimeout(1.seconds,
             writeln("conn: received ws message: " ~ msg);
         }
     );

     if (received) {
         writeln("received!");
     }
     else {
         writeln("timed out...");
         // stuff?
     }
