How can I call the extension function when I have a member function of the same name but taking a differently-typed function parameter?

class C {
    fun foo(block: Int.() -> Unit) {
        123.block()
    }
}

fun C.foo(block: String.() -> Unit) {
    "hello".block()
}

fun main() {
    val c = C()
    c.foo {
        println((this as String).length)  // this is Int, want String
    }
}

I think you probably have to use an anonymous function instead of a lambda, or do use the trailing lambda and cast the lambda to the correct type

[Ruckus]

You can get around it with an import:

import foo as fooString

class C {
    fun foo(block: Int.() -> Unit) {
        123.block()
    }
}

fun C.foo(block: String.() -> Unit) {
    "hello".block()
}

fun main() {
    val c = C()
    c.fooString {
        println(length)
    }
}
