I have a lambda with its `it` value parameter being used in its body. ```foo.increase { it + 42 ...

I have a lambda with its it value parameter being used in its body.

foo.increase {
   it + 42
}

I want to create a different lambda, and replace increase with it, but reusing its body

foo.newLambda {
    it + 42
}

The problem is the it is not in the mapper so it fails. Indeed I got issues related to the parent in the IrReturn when I tested it without using it and I did the next workaround:

this.body = declarationIrBuilder(this).irBlockBody {
    for (original in originalStatements) {
        val statement: IrStatement =
            if (original is IrReturn) irReturn(original.value)
            else original
        +statement
    }
}

Is there a simple way to just copy the body an map the parent and the value parameters? I tried deepCopyWithSymbols and indicating a parent but it did not work.

Instead of copying the body I am copying the whole function and it works

[Javier]

val expressionLambdaFunction: IrSimpleFunction =
    expressionLambda?.deepCopyWithSymbols(updateCallParent)?.function
