_dynamicReplacement could not call origin async method

[Whirlwind]

Xcode 14.1, swift-driver version: 1.62.15 Apple Swift version 5.7.1 (swiftlang-5.7.1.135.3 clang-1400.0.29.51)

dynamic
public func runCommander() async {
    printf("1")
}

@_dynamicReplacement(for: runCommander())
public func core_runCommander() async {
    await runCommander()
}

I get a deadloop:

I try other methods, same wrong.

This looks like correct behavior, by telling that core_runCommander is a dynamic replacement for runCommander calling runCommander means calling core_runCommander which make this function a recursive call.

I don't think so. If I remove the async, call the runCommander will call the origin method:

dynamic
public func runCommander() {
    printf("1")
}

@_dynamicReplacement(for: runCommander())
public func core_runCommander() {
    runCommander()
}

It will print the 1.

If you are right, what should I do when calling the origin method?

I found a test: https://github.com/apple/swift/blob/7123d2614b5f222d03b3762cb110d27a9dd98e24/test/Interpreter/Inputs/dynamic_replacement_chaining_B.swift
It will call the origin method by origin name.

Ok, looks like I misunderstood the feature behavior

[LucianoPAlmeida]

Yeah this looks indeed a bug

Any process?
