Steve:

Sorry for the delay in replying. That is the runtime removing the shared 
from the entire AA, not our code. I point out the change that induces 
this with a link to github.

Should I move this discussion to the main D group? My primary concerns are:

0. Ask if it is intended behavior that the runtime cannot handle a 
shared AA post 2.086.1?

1. Report this as bug

2. Ask why this commit ("object: Declare private struct AA and fix aaA 
function signatures ") not mentioned in the changelog for 2.087?

Thanks in advance
