Why does the check fail? I would expect Foo.bar() to be in the memberExtensionFunctions list.
I also tried declaredMemberExtensionFunction (though I’m not sure what the difference is) with the same result. Am I missing something?
The list contains member extension functions, i.e. those that are both members and extensions at the same time:
class C {
fun D.ext() {} // this is a member extension function
}
