fun a(param:Int){
   val v = param
}
//transformed to
fun a(param:State<Int>){
   val v = param.value
}

To do such a transformation, I need to change the param type first. But I don't know how to handle the function body. The IR for

param

before transformation is

Get_Var

, and the after for

param.value

is

Call

, it seems I cannot directly use

visitGetValue

to do it. Is there another methods to use?

to visit the

param.value

you could use

visitCall

to handle

param.value

if this was the question.
