--- Comment #5 from Dlang Bot <dlang-bot@dlang.rocks> --- dlang/dmd pull request #11442 "Fix Issue 12223 - __traits(getMember,...) needed for aliases" was merged into master: - da1a31509f43547a89fd7cd694499548ba345ee0 by Richard Manthorpe: Issue 12223 - __traits(getMember,...) needed for aliases Add `__traits(child, p, c)` to interpret `c` with the `this` context set to `p`. This is the opposite of `__traits(parent, c)`. `c` should be a symbol mising it's `this` context, such an an alias to a member of `p`. https://github.com/dlang/dmd/pull/11442 --
