This looks like the bug report you are referring to:  
https://issues.dlang.org/show_bug.cgi?id=18944

I understand that the specification defines the current behavior 
and provides a workaround, but what's the justification for that 
behavior?  Is it hygiene?

I've been interested in improving mixins for reasons discussed in 
the interpolated strings PR 
(https://github.com/dlang/dmd/pull/7988) and this discussion 
about library-implemented properties 
(https://forum.dlang.org/post/mqveusvzkmkshrzwsgjy@forum.dlang.org).

Perhaps there's an opportunity here for a language improvement 
that would help all of these use cases.
