auto limitation?

I suggest to file a bug:


auto foo(bool b) {
     final switch (b) {
         case true:
             return 10;
         case false:
             return 20.0;
     }
}
void main() {
     import std.stdio: writeln;
     writeln(foo(true));
     writeln(foo(false));
}


The acceptable results are a compile-time error for type 
mismatch, or a conversion of both literals to double. Probably 
the second is better. But a silent bit-level cast is not 
acceptable.
