My concern is this problem is a problem with the implicit conversion of a 
delegate to `pure`. I suggest that problem get fixed before going any further 
with this. The reason is the bug examples seem to rely on such an implicit 
conversion.

If the same problem can be demonstrated without using pure attributes, then it 
is a problem separate from the `pure` inheritance issue.

Forgive me for asserting that many, many of the issues that have been posted to 
bugzilla turned out to not be the problem the submitter thought it was, but 
something unexpected which was revealed when the problem submission was pared 
down to a minimal example.
