Quick assist to change between if/else if/else tree and switch (in both directions)

[ChristianKleineidam]

Sometimes I have code like:

if(count==1){
  return foo();
} else if (count==2){
  return bar();
} else{
 throw ArgumentError("$count isn't a valid count");
} 

And I think the code would be more concise as:

switch (count){
  case 1: return foo();
  case 2: return bar();
  default: throw ArgumentError("$count isn't a valid count");
}

It would be great if I would have a quick assist option to change both the first into the second and the second into the first (as sometimes I decide I want ifs after already having written switch statements. Of course when the if tree has a form that can't simply be converted into a switch statements no quick assist option would be shown.

Today for the switch there is already an assist:

Maybe this could now be simpler since it would only need to convert the if == to case and the current assist could do the rest.
