Yes, this does work for arrays of structs. Provided that you've passed 
in the type info for the struct when doing the manual allocation, it 
should call the destructor without anything extra needing to be done on 
the user's part.

Appender already uses the type info's destroy, so it shouldn't have any 
issues, as I already had to account for that.

As I mentioned elsewhere, as long as the existing code is calling 
destroy, and not calling the finalizer directly, then yes, it will play 
nice, and only call the finalizer once.
