Hardly anyone wants switch to be a better if-else ladder.

I don't think this is what is being asked for.
switch(x){
case a:
...;
break;
case b:
...;
break;
default: break;
}
->
switch(x.toHash()){
case a.toHash():
if(x!=a) goto default;
...;
break;
case b.toHash():
if(x!=b) goto default;
...;
break;
default: break;
}
(a and b are known at compile time here, and so are their hash
values. Hash collisions between e.g. a and b would need to be
dealt with of course.)
Yes, this is what I meant.
