fun foo() = println("No receiver")
fun Int.foo() = println("My receiver is $this")

with(42) { foo() } // will print 'My receiver is 42' but I want 'No receiver'

Is it somehow possible to call the function without receiver, although one is given by the current scope?

if foo() is not top level fun, then you can specify it via `this`:

with(42) { [e-mail]() }

Depends on more context.
For example you can qualify it if it is a top-level function like

package bar

fun foo() = println("No receiver")
fun Int.foo() = println("My receiver is $this")

fun main(){
    with(42) { bar.foo() }
}

Or if the foo is a local function it will also win:

fun Int.foo() = println("My receiver is $this")

fun main(){
    fun foo() = println("No receiver")
    with(42) { foo() }
}

A combination of the two:

package bar

fun foo() = println("No receiver")
fun Int.foo() = println("My receiver is $this")

fun main(){
    fun foo() = bar.foo()
    with(42) { foo() }
}

Or you can qualify the this reference if possible like

class Foo {
    fun foo() = println("No receiver")
    fun Int.foo() = println("My receiver is $this")

    fun main(){
        with(42) { [e-mail]() }
    }    
}
fun main() = Foo().main()

[Astronaut4449]

fun foo() = println("No receiver")
fun Int.foo() = println("My receiver is $this")

fun main() {
    with(42) { foo() } // will print 'My receiver is 42' but I want 'No receiver'
}

Sorry for being so scarce on the context.

Both functions are top level declarations.

Anything wrong with the options I gave you?

Thank you. I guess I need to use the package name. Unfortunately when I tested this I used no package 🤣
