I proposed something very similar in this thread[1], except I 
proposed a solution that is fully backwards-compatible except the 
rare case when exceptions are escaped, in which case it causes a 
compile-time error. Might be worth a look.

I don't think it's acceptable that code using Phobos is suddenly 
leaking until they add the new manual cleanup call.
