           Summary: Add weak references to Phobos/druntime
           Product: D
           Version: future
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Phobos
        AssignedTo: nobody puremagic.com
        ReportedBy: nfxjfg gmail.com



Just that.

The Java API documentation may provide a good starting point as to what weak
references should be able to do:
http://java.sun.com/javase/7/docs/api/java/lang/ref/WeakReference.html

Note that finalizers and the "hidden" rt_attach.../detach... functions are
highly unsafe and hard to get right. As an example what can go wrong if users
try to implement their own weak references, see bug 4150.

Even worse GC lock/unlock aren't parts of a druntime user API so one have to
use ugly things like calling addRange/removeRange to ensure the memory will not
be collected.
