Understood, but I'm not sure that's as big an issue as you think.  I exchanged 
some private emails with Manu and with Adam Ruppe, on how RNGs-as-final-classes 
might play with games or embedded programming, and I think the consensus was 
that it wasn't a big deal, so long as all the allocation happened up front.

Adam suggested that e.g. one could avoid GC by allocating memory and using 
emplace(), so as long as the class is compatible with that approach, it's fine.
