Sealed classes - would you want them in D? (v2)

[Neia Neutuladh]

Can you provide even one anecdote where this would have been 
useful and the workaround that has been suggested to you multiple 
times (putting the type in its own module) wouldn't have worked 
or would have caused other problems?

I mean, usually we need to do a cost/benefit analysis, and the 
first part of that, the one that people generally do 
instinctively, is try to describe the benefit. You seem to view 
the benefit as self-evident, but we've told you many times that 
it isn't self-evident to us, so you have more work to do if you 
want to convince anyone.

If you just want to vent, though, you might say that explicitly.
