Expected behavior It should compile successfully or offer a meaningful error message

ZacSweers commented 1 week ago

figured this out after hopping into a debugger during compilation. The actual issue was a missing actual declaration for a compose function. Possibly worth closing this, but also think it's worth an improved error message

Same usually, usually missing actual throws a readable error. A better error would be appreciated
