Issue ID: 18944 Summary: Mixing in new overloads of a function in an object won't resolve the overloads correctly Product: D Version: D2 Hardware: x86_64 OS: All Status: NEW Severity: critical Priority: P1 Component: dmd Assignee: nob...@puremagic.com Reporter: goober...@gmail.com Seems related to ancient issue 9235, but not quote the same. Any additional overloads of a function that are called from the object itself won't resolve. Code example at https://run.dlang.io/is/a85Lbq Changing the code so that every instance of the foo overload is mixed in results in the program compiling and running as expected. I came across this when trying to use mixins as a dodgy way to replicate C#'s partial classes. So this is quite bad as far as usability concerns go.
