Hello,
I've run into a situation and I've been trying to figure it out. I have an extension function declared at the top level in my module, and I have an extension function declared within a class' scope. When I call a method that changes the receiver to this scope, I can't figure out how to access the top-level function.
An example:

fun MyObject.get(str: String): String {
        return get(str) {}
    }

class Scope {
        operator fun Any.get(str: String): Int = 1
}

// within method body
val myObject = MyObject()
val scope = Scope()

with(scope) {
  myObject.get("abc") // calls Scope's get()
}

How do I tell the compiler to call MyObject.get()? Suppose that both extension functions are define din libraries, so I can't easily change those names.

Testing here, if I'm in a method call I can forcibly change the receiver:

with(scope) {
  with(this@methodClass) {
    myObject.get("abc") // calls MyObject.get()
  }
}

But it doesn't seem great, and won't work if I don't have a this.

you have endless recursion in MyObject.get I don't understand what you want to achieve there.

[obobo]

I want to call the first get(). The recursion was a mistake while I was simplifying my example, ignore it.

assuming

fun MyObject.get(str: String): String {
	println("MyObject extension get: $str")
	return str
}

You can easily avoid the problem you describe:

import com.example.MyObject
import com.example.Scope
import com.example.get as myGet

// within method body
val myObject = MyObject()
val scope = Scope()

with(scope) {
	myObject.myGet("abc") // prints "MyObject extension get: abc"
}

Ah, good, that answers it, thanks.

Sure, this is a very useful trick along with `typealias`es 🙂

[obobo]

Yeah, I had forgotten that you can alias imports
