D gc on local objects

[Adam D. Ruppe via Digitalmars-d]

This is one of the things the `scope` storage class on local 
variables can do, but since it isn't implemented properly, it is 
not memory safe and thus its usage is deprecated.

I really really really want to see scope be fully implemented, 
including not allowing a reference to the variable to escape the 
scope, but this is easier said than done.
